Pondering the Possibilities

At the beginning of your upkeep, look at the top
three cards of your library. Put one of them into
your hand and the rest on the bottom of your
library in any order.
At the beginning of your end step, sacrifice
Pondering the Possibilities, unless you remove
a +1/+1 counter from a creature you control.
Devising an effective plan is the only way to beat the
Demon lords of Erebor.
