Snow Creature -- Spider
Frostweb Spider can block as though it had flying.
Whenever Frostweb Spider blocks a creature with flying, put a +1/+1 counter on Frostweb Spider at end of combat.
1/3
So lets say the Frost web spider blocks a Sewn-Eye Drake (3/1 creature with flying)
Does the frostweb spider live or die? It says the counter comes in end of combat will that prevent the frostweb spider from going to graveyard or is that too late?
