You and target opponent each flip a coin. Mana Clash deals 1 damage to each player whose coin comes up tails. Repeat this process until both players' coins come up heads on the same flip.
First strike, protection from black and from red (This creature deals combat damage before creatures without first strike. It can't be blocked, targeted, dealt damage, or enchanted by anything black or red.)
Change the text of target permanent by replacing all instances of one color word with another or one basic land type with another. (For example, you may change "nonblack creature" to "nongreen creature" or "forestwalk" to "islandwalk." This effect lasts indefinitely.)
At the beginning of each player's draw step, that player puts the cards in their hand on the bottom of their library in any order, then draws that many cards.
Flying (This creature can't be blocked except by creatures with flying or reach.): Regenerate Will-o'-the-Wisp. (The next time this creature would be destroyed this turn, instead tap it, remove it from combat, and heal all damage on it.)
Flying (This creature can't be blocked except by creatures with flying or reach.)Nightmare's power and toughness are each equal to the number of Swamps you control.
