Ravaging Riftwurm

Flash; convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for 1 or one mana of that creature's color.) Flying When this creature enters, prevent the next 5 damage that would be dealt this turn to any number of targets, divided as you choose.

Shadow (This creature can block or be blocked by only creatures with shadow.) Sacrifice this creature: You gain 4 life. Activate only during your upkeep.

At the beginning of your upkeep, if you control no permanents other than this enchantment and have no cards in hand, you win the game.

Until your next turn, creatures can't attack you. Exile Chronomantic Escape with three time counters on it. Suspend 3—2W (Rather than cast this card from your hand, you may pay 2W and exile it with three time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost.)

Choose one — • Remove two time counters from each permanent and each suspended card. • Put two time counters on each permanent with a time counter on it and each suspended card.

Cast this spell only if you control fewer creatures than each opponent. Create three 1/1 white Soldier creature tokens.

Flash (You may cast this spell any time you could cast an instant.) Enchant creature Enchanted creature gets +0/+2.

The next time a source of your choice would deal damage to you this turn, prevent that damage. You gain life equal to the damage prevented this way. At the beginning of your next upkeep, pay 1WW. If you don't, you lose the game.
