I would drop blue altogether and make this deck white-red. That way you can set the combo off yourself, rather than wait for an opponent/the opponent to walk into it.

if you want to give them the activated abilities as though they had haste, why not just give them haste and be done with it? go with Fervor if you want haste.

Cards I would take out:
2x Krenko, Mob Boss
4x Arms Dealer (there are better places those sacked goblins can go)
4x Flame Slash

Cards for consideration for this deck:
Seige Gang Commander
Brightstone Ritual
Clickslither
Reckless One
Lightning Crafter (possible replacement for Lightning Bolt)
Slate of Ancestry (since you'll be popping out a crap ton of goblins)
Fling
Goblin Lookout
Goblin War Strike
Mogg War Marshall

Since this is your deck, however, this is all for your consideration

Gather the Townsfolk?

As far as I can tell, the only part of this that may need tweaking (at your discretion of course) is creatures.
1. I would drop the number of Aurelia's down to 1. You don't want a six drop floating in your hand at a time of crisis, and usually by them time she hits the field, the game has either been over for awhile or it's game over in your favor.
2. I would drop Champion of the Parish. You aren't really running a human heavy creature base, so he won't be as handy to you as you may think.
3. I would drop Tajic down to 2. A four cost 7/7 indescructible may sound nice, but that only goes off when he's attacking with others, which you need to make room for cheaper critters in this deck.
4. I would drop a Spark Trooper (bringing you to two). It's a beautiful thing, but it only lasts a turn, and you don't want to leave yourself wide open longer than you have to.
5. If price is an issue, ignore this bullet. I would get two more Reckoner's. It's too great of a Boros card to not have 4 of in a boros standard deck.
6. To compensate for the creatures i've recommended you take it (assuming you don't get the 2 reckoner's) I'd either get a playset of Legion Loyalist, or finish out the playset of the Halbediers, Vaishino Firstblades, Skyknight Legionnaires, and Boros Elite.
7. Take a look at Aurelia's Fury, see if it's something you would like to use in this deck.

Other than this man, it looks great!

thanks man! It wouldn't be well built without all the helpful comments and tips on how to make it so much better!

this deck is pretty much going to be for casual play lol

The deck list has been updated once again and (hopefully) for the final time. Thank you all so much for helping me with this deck. It's an idea I've had for a while now and I'm glad to see it come to fruition

Updated again. Added Jin-Gitaxias for added hand control, draw, and discard

deck list updated again with adjusted numbers! this better?

Deck list has been updated! I decided to go reanimator with it! Tell me what you think og it now!

I'm not sure if the reiterate and seething song combo works because you can (to my knowledge) only pay that buyback cost once, and then reiterate bounces back AFTER spells resolve, so seething song would be gone before you could copy it again. I'm not entirely sure though

Since you're having them draw so much, why not add Underworld Dreams?

If you're going with a goblin theme, take out Lightning Mauler and replace it with Fervor. One cost more, leaves you room for more Goblins.

I'd take out those Landslides. There's a lot of players that play control and if that gets countered, you're out some mana, and that's bad in any situation. I'd throw in 2 more burst lightning and 3 more galvanic blast to compensate

infinite loop with Vizkopa Guildmage's second ability and Exquisite blood? possibly? not quite sure. otherwise id replace Victim of NIght with Murder. MUrder may cost one more, but it covers a wider array of creatures to kill, thus is a safer choice in my opinion. I'd also replace Ultimate Price with Doom Blade. Same cost, to kill a wider array of creatures. If you don't care if this deck stays standard id replace Gravepurge with Aphotic Wisps. Give one of your critters fear AND draw a card for two less mana? I'd take that! Otherwise i'd do Cremate in Gravepurge's stead. get to draw a card for one mana and at least keeps them from getting nasty stuff back from their graveyard. Smite can be handy but can be very situational. I'd add in some Executioner's Swing, which is also a little situational but can help you out early in the game. besides all that, this deck could work i think. hope all this helps!

very good point, i'd forgotten about that

ok so added two Spinneret slivers because i played this deck and got stomped by fliers. I didn't add winged sliver because, with shadow sliver, they pretty much cant be blocked anyway, giving them flying seems a bit overkill (even for slivers) but giving them reach seems exceptionally handy, especially if the game goes on a ways and they get real big

I took out the 3 Frenzy Slivers (added damage that wasnt really necessary) and replaced them with Synchronous (vigilance) and Essence (lifelink), synch to add more blocking capability, and essence for the added life. Both of these are because i know as soon as opposing players see me playing a sliver deck, they're gonna jump my ass, and I want to be ready.

thanks for all the help man! You and Jack Miton really helped pull this deck together. As it is now, even with the guildgates, ive tried this deck out (proxies) and it works fast and it works like a charm. I'm happy where its at, but if i do have any other questions, I'll let you know! thanks again for the help!
