Share Strength

Choose two target creatures you control. Exile
one of those creatures until the next end phase
and put X +1/+1 counters on the other, where X
is the exiled creature's power. At the beginning
of the next end step, remove all +1/+1 counters
from that creature.

a lot we can learn from them." - Rowan Kenrith
