Junction of Iridescence

This land enters tapped unless it is the second land you have played this turn.

{t}: Add {r}{w}. This land does 2 damage to you.

{4}{t}: Place 1 loot counter on this land, then create 2 treasure tokens for every loot counter you control. Until the end of the turn if you would sacrifice a treasure token to add mana, add twice that amount of mana, instead.
