I tried to make a budget control/combo deck with artifacts, based on Spine of Ish Sah. It does win games, unless i face some heavy artifact destroy or control decks.
I could use some opinions on how to improve it further, from card swaps to a change on the number they exist on the deck or sideboard
Card description
Creatures
Myr battlesphere: Good for the blockers it brings, as well as the ability to do 12 damage in 1 round
Steel Hellkite: it can be used as a mass Spine of Ish sah, although easy to get removed and less versatile
Chimeric mass: Can be an early blocker, and a finisher if the other 2 are not available for some reason. Target of trinket mage late game too
Trinket mage: Targets Everflowing chalices(mostly), elixir of immortality, or chimeric mass
Treasure mage: Targets finishers, Spine of Ish sah and contagion engine
Artifacts
Contagion Engine: double proliferate, mass creature removal on demande (via trasure mage)
Elixir of immortality: Gives some more time against burn/aggro decks, also returning my graveyard to library is nice
Everflowing chalice/Semblance Anvil/Shpere of the suns: Much needed mana accelarators, in order to be able to chain Spine from turn 4 at best
Ichor wellspring/Throne of geth: card advantage and proliferate(Tezzeret's gambit does both, but tried it and doesnt work so well due to more expensive and less on demand proliferate)
Tumble magnet: Prevents whatever mustnt attack or tap until it gets removed
Spells
Mana leak: Because i cant think playing blue without some counterspell and also to protect my combo
Preordain: nought said
Black sun's zenith: reusable mass removal with counters, great with proliferate
Blue sun's zenith: Endgame i have a lot of mana, and whats better than convert it to cards
Sideboard
Black Sun's Zenith: for aggro decks
Negate/Spell pierce: instead of mana leak against control decks, or ones who doesnt have many powerfull creatures
Torpor orb: Against Stoneforge mystics, Deceiver exarchs or other creatures that does nasty things when they enter the battlefield. I sideboard trinket/treasure mages and Myr battlesphere. If i draw more than 1, it can be used for proliferate or life (via Throne or Phyrexia's core)
Triskelion: another finisher when i sb Myr battlesphere
Changes:
I have been thinking of what counterspells to put in main deck like
Stoic rebuttal (much better endgame, but more expensive early),
Dispel (against counters, the biggest weakness of the deck),
Spell pierce (less reliable than dispel, but with more applications)
Mana leak may be the best counterspell now, but I dont have much mana in the begining to use it and in the end the opponent can pay for 3 mana.
Wurmcoil engine could be a possible finisher, but i dont know it it could be better than those already existant, and in what cases to call it (via treasure mage)
I am open to comments and suggestions on the deck, ty for your time
