My plan is not to lock opponent out of the game but just to slow him down enough so the beatdown plan can be run. So, technically it is not a prison deck (like a stax deck) but more tempo oriented. However name is not really important.

Antiquities war can be interesting but i am not really sure it goes where i want. Still, I will give it a quick try if i can.

I fully agree that Masticore is not good here. I have enough ways to deal with planeswalker now that i run eliminate (+stonecoil serpent for multicolored ones).

I tested etched champion when i used to play steel stompy and i was a bit disapointed. i found it interesting only when using equipment (jitte or whatever).

Here, i want a stronger beater (masticore are 3/4 that is quite nice). My next test will be using Traxos but (because of the curve) i would prefer a creature with cc3 instead of cc4.
