Scab-Clan Hedgekeeper

Haste
When Scab-Clan Hedgekeeper enters the battlefield, you may put three +1/+1 counters on target Gate you control. If you do, that land becomes a 0/0 Elemental creature with haste that's still a land.
"It'll either creep alongside your courts or cultivate in the alleys and spires of Ravnica itself."
