Wrenn Reborn

Lands you control enter the battlefield with
shield counters on them.
Whenever a land you control attacks, create a
token that's a copy of it that's attacking.
Sacrifice it at the beginning of the next end step.
At the beginning of combat on your turn, target
land you control becomes a creature with base
power and toughness 3/3 until end of turn. It
gains vigilance until end of turn.
