Good Daughter Dooley

Only mana produced by lands may be used to pay
Good Daughter Dooley's mana cost.

You and lands you control have ward {x}. Whenever
an opponent attacks you, they must pay {x}.

At the beginning of combat on each player's turn,
target land you control becomes a 1/1 green
Elemental creature with haste and "this creature
gets +1/+1 for each land you control" until end of
turn. It is still a land.
