Dreadmoon Conduit

Dreadmoon Conduit gets +1/+1 for each
nonbasic land an opponent controls.
Whenever Dreadmoon Conduit deals combat
damage to a player, create a colorless Dreadmoon enchantment token with "Whenever a nonbasic
land becomes tapped, that land's controller loses
2 life if Dreadmoon is untapped, then tap
Dreadmoon."
