Dissolve? Might as well go all out if you want control...

Dissolve requires 2 blue, and costs 3 mana, so it would be hard to play the same turn we play Spellheart Chimera. Though if you prove it is better than Temur Charm I might swap them.

requires one kind of mana and aids in deckcycling, but charms are 99% of the time better

seems like a cool deck to play it would be interesting in my meta with a bunch of abzan agro and sulti control

Some things that will make your Spellheart Chimera even more painful:

Fall of the Hammer: For when absolutely obliterating something once just isn't enough.

Runechanter's Pike: For those pesky deathtouch blockers.

Rush of Blood: For life-gain decks.

edit: I would say Soul's Fire over Fall of the Hammer, due to targeting.

Those are not for standard though. Someday, there will be a modern version of this deck. Thanks for suggestions anyway.

Seems like a lot of fun against a lot of decks. My only problem with the deck is that Spellheart Chimera will only have 3 toughness letting a simple Lightning Strike take down your creatures. I don't know how you would counter that without using up all of your counters against removal spells.

In current standard, the only cheap removal spells are Lightning Strike, Bile Blight and Ulcerate. Most decks don't play many. Other removal spells aren't such a problem, as they cost a lot and the decks are limited to 1 removal/turn before late game. Chimera swings for a lot, so only 1 hit can put our opponent in burn range.But yeah, decks that abuse removal (Mardu/Jeskai Midrange) are quite a problem for this deck. Don't know how to fight that yet.

In my mind I would prefer this in jeski because this way you can gain white for protection for temur charm and hornets nest do either feat of restiance or gods willing for protection of the chimera because this way it not only gets bigger but protects I would do the feat because then its toughness also would go up so they would have do a 2 for 1 2 lightning strikes/2 magma jets for it so it is not a far trade and maybe also do like some unblockable so it can get in easier with no blocks even though it has trample

That might work, but be aware that Gods Willing, Feat of Resistance and similar cards just don't do anything if we don't have chimera in play. White also lacks cards like Scout the Borders.
If you try the Jeskai version, let me know how it goes. For now, I stick with green.

Wood Sage to dig for your chimera, maybe?

no, Wood Elemental
