what bothers me about this is how outlast can only be used at sorcery speed meaning he doesnt help reuse that ability, which seems to be what he should be designed to take advantage of.
But despite being able to pay it over multiple turns, it is a dead top deck, and all needs to be paid at sorcery speed. What happens when you spend 3 turns turning this on and in response, I kill your equipped creature with ulcerate? Last known info makes the creature remembered as a 0/0 when the ability resolved, so you spent 3 turns working on sacrificing a creature to bolt me to the face. Even if you spend just 2 turns setting it up, I can just drown in sorrow you, now you are stuck with one big creature with defender. Big deal. You spend 3 more turns developing your board and I aetherspout it. or any other mass removal spell. Yes you can get 9 mana out on turn 6 in green, but if you do, you have no big creatures to put this on. The problem is to make this worthwhile, you need at least one big creature, and multiple small creatures plus lots of mana.
Not much of a Kessig Wolf Run, but rather Craterhoof Behemoth. You invest a lot of mana, preferably with mana dorks and end up with a board full of big creatures. This has the advantage of being an artifact and having its cost split up, but the disadvantage of needing a ~3/3 body to activate.
Still probably too weak for Standard but lets wait until we see how good the mana in Khans really is.
The closest thing this resembles is craterhoof behemoth, but the thing is, that craterhoof behemoth pumped your mana dorks based on the number of mana dorks you had, not a creatures power, so this actually requires you to have a bunch of mana dorks, and another big dude as well and this can't have it's cost cheated through reanimation. this card just has you begging to be time walked time and time again. In limited, sure, where there is very little mass removal, or even all that much great spot removal, this will be good, but if you think this has any chance in standard, or even block you are crazy.
the thing is for 7 mana, you are better off running aetherling. Tromokrasis is really just an 8/8 for 7. that's really not good enough. it still is vulnerable to ultimate price and most other played removal when it attacks, and just doesn't do enough. I mean even Stormtide leviathan stops them from swinging back at you.
my guess is we see fetches in the next expert level set or the one following it or wizards risks cutting into those who wish to play modern with 100 dollar lands necessary.
and this would not be a 4 of in every white deck as well as many non white decks to make creatures bolt proof because???
