Dash/token Pain

Feedback is appreciated. The card listing is the actual stats but I want two more [Flamerush Rider]s and another [Purphoros, God of the Forge] to replace the [Warbringer]s.
Had a friend make a black/red deck with the same basic concept, so here is my take on it in standard mono red!
Obviously the point is to inflict as much pain as possible with creatures entering the battlefield via [Purphoros, God of the Forge] and [Impact Tremors]. The secondary strategy is to hit the opponent as much as possible with your dashed creatures.

I tried it out and I almost always have atleast 3 damage per creature entering the battlefield with [Purphoros, God of the Forge] and [Impact Tremors], so through these two we can estimate that at a minimum
IMPORTANT: Don't attack with all the tokens, because you need blockers. I am guilty of this.
[Hordeling Outburst] = 9 damage and [Dragon Fodder] = 6 damage
I try to never use [Howl of the Horde] with these two ^ without having attacked first so if you use it, then [Dragon Fodder] is 18 damage on avg. and [Hordeling Outburst] is 27. not bad for 5 and 6 mana.
There is also this fun stuff:
[Twinflame] on [Flamerush Rider] then attack = total 9 damage + combat damage
[Twinflame] on [Goblin Rabblemaster] then start combat = ^same
use [Howl of the Horde] before combat with [Twinflame] and either of the above two for more fun.
[Radiant Fountain] is really just there for the "Why not?" factor. Replace with mountains if you don't like it.
All the instants in the sidedeck can be swapped with [Magma Jet] circumstantially and [Descent of the Dragons] is always a fun thing for later in the game if it lasts that long. Use it on yourself to get dragons and trigger your bonus damage from [Purphoros, God of the Forge] and [Impact Tremors].
