Icingdeath has nothing to do with overindulging in cakes, but is a four-mana White 4/3 with flying and vigilance
They will, as is the way with trading games, be split into commons, rare, super rare and legendary with foil cards too for that added sparkle

When you attack, both players decide what side of the battlefield their creatures go to, and any creatures on one side of the battlefield cannot block or be blocked by creatures on the other (represented by the fact that they're on opposite sides of the river)
It fixes and ramps your mana effectively, and actually can become a 3/3 in the later stages of the game, and thats enough size to at least be relevant all game long
