Target blocking creature gets +7/+7 until end of turn.

At the beginning of your upkeep, if an opponent controls more lands than you, you may search your library for up to three basic land cards, reveal them, put them into your hand, then shuffle.

Enchant creature (Target a creature as you cast this. This card enters attached to that creature.)
Enchanted creature gets +0/+2 and has reach. (It can block creatures with flying.)

Change the text of target spell or permanent by replacing all instances of one basic land type with another. (For example, you may change "swampwalk" to "plainswalk." This effect lasts indefinitely.)

Target spell or permanent becomes blue. (Mana symbols on that permanent remain unchanged.)

Earthquake deals X damage to each creature without flying and each player.

At the beginning of your upkeep, you gain X life, where X is the number of cards in your hand minus 4.

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.

Target spell or permanent becomes white. (Mana symbols on that permanent remain unchanged.)

Flying (This creature can't be blocked except by creatures with flying or reach.)
: Regenerate this creature. (The next time this creature would be destroyed this turn, instead tap it, remove it from combat, and heal all damage on it.)

, : Target creature gains banding until end of turn. (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding a player controls are blocking or being blocked by a creature, that player divides that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.)

Each player shuffles the cards from their hand into their library, then draws that many cards.

Change the text of target spell or permanent by replacing all instances of one color word with another. (For example, you may change "target black spell" to "target blue spell." This effect lasts indefinitely.)

Banding (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding you control are blocking or being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.)

Target spell or permanent becomes black. (Mana symbols on that permanent remain unchanged.)
