Commander 2011

Forestwalk (This creature can't be blocked as long as defending player controls a Forest.) As an additional cost to cast creature spells, you may pay any amount of mana. If you do, that creature enters with that many additional +1/+1 counters on it.

Morph 4U (You may cast this card face down as a 2/2 creature for 3. Turn it face up any time for its morph cost.) When this creature is turned face up, you may exchange control of target creature you control and target creature an opponent controls.

Radiance — Cleansing Beam deals 2 damage to target creature and each other creature that shares a color with it.

If a noncreature permanent under your control was destroyed this turn by a spell or ability an opponent controlled, you may pay G rather than pay this spell's mana cost. Create four 1/1 green Snake creature tokens.

Join forces — Starting with you, each player may pay any amount of mana. Each player searches their library for up to X basic land cards, where X is the total amount of mana paid this way, puts them onto the battlefield tapped, then shuffles.

Target creature gets +4/+2 and gains trample until end of turn.

Multikicker 1 (You may pay an additional 1 any number of times as you cast this spell.) Choose any target, then choose another target for each time this spell was kicked. Comet Storm deals X damage to each of them.

T: Add one mana of any color in your commander's color identity.

Target player gains 2 life for each creature on the battlefield.

Flying Whenever this creature attacks, each player chooses a card name. Then each player reveals the top card of their library. If the card a player revealed has the name they chose, that player puts it into their hand. If it doesn't, that player puts it on the bottom of their library.

Vigilance When this creature enters, look at the top three cards of your library, then put one of them into your hand and the rest on the bottom of your library in any order. When this creature enters, sacrifice it unless W was spent to cast it.

At the beginning of each upkeep, put a strife counter on this enchantment. Attacking creatures get +1/+0 for each strife counter on this enchantment. Blocking creatures you control get +1/+0 for each strife counter on this enchantment.

Search your library for up to two basic land cards, reveal those cards, put one onto the battlefield tapped and the other into your hand, then shuffle.

Deathtouch Skip your draw step. At the beginning of your upkeep, if you have fewer than seven cards in hand, draw cards equal to the difference.

Flying When this creature enters, destroy target nonblack creature. It can't be regenerated.

Indestructible (Effects that say "destroy" don't destroy this artifact.) T: Add one mana of any color.

Reach (This creature can block creatures with flying.) Deathtouch (Any amount of damage this deals to a creature is enough to destroy it.)

Vanishing 3 (This creature enters with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.) When this creature enters or leaves the battlefield, return another target creature card from your graveyard to your hand.

Destroy target nonblack creature. It can't be regenerated. Create X 1/1 green Saproling creature tokens, where X is that creature's mana value.

Each player other than target player creates a 5/5 red Dragon creature token with flying.

When this creature enters, return to your hand the creature card in your graveyard with the greatest power. If two or more cards are tied for greatest power, you choose one of them.

Search your library for a card, put that card into your hand, then shuffle.

This land enters tapped. When this land enters, return a land you control to its owner's hand. T: Add UB.

1, T: Add UB.
