Dies to Removal

I'm also really high on Arbor Colossus right now. Laughs at Sarkhan, Stormbreath, and most of the RGx dudes, and is almost impossible for them to deal with after going monstrous.

Nykthos being a winmore makes sense. How has Temur Charm been testing? Seems stupid with Prophet.

I think once more people wise up you'll sed Crater's Claws in GRx decks. They're going to have to interact with other creatures somehow and it's their best option since it's never really dead, scales with game length, and does respectable damage for the cost when you have a fatty out (almost always).

I will say that I think Nykthos would really make the deck tick. Reid Duke was running Yisan with Nykthos and he was able to do some outrageous things with it like get multiple Yisan activations in one turn, get a huge PolyK activation, or even play an Arbor Colossus and monstrous it in the same turn. You could swap the Caryatids for Voyaging Satyr and found room for 3 Nykthos. It would just make the number of red sources more shaky.

Definitely one of the better Yisan brews I've seen so far. I tried drawing up a UG build earlier so I'm interested in whether or not this can be a thing. I like Chord as another way to find Yisan or just another answer.

Best thing about this deck is that spot removal is sparce and expensive, so Yisan will live a lot longer on average. And even if he doesn't you can just go beatdown with you fat threats. They either kill Yisan and leave themselves open to Knuckledude or let him live to find Knuckledude anyway.
