{T}, Sacrifice this artifact: Add three mana of any one color.

You may look at the top card of your library any time. You may play lands and cast spells from the top of your library. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost. {T}, Sacrifice ten nonland permanents: Each opponent loses 10 life.

Avoidance — Whenever you cast a noncreature spell, exile up to one target nonland permanent you control, then return that card to the battlefield under its owner's control.

Whenever this creature deals combat damage to a player or planeswalker, draw a card. Discard a card: Put a +1/+1 counter on this creature. Exile three cards from your graveyard: This creature gains flying until end of turn.

({U/P} can be paid with either {U} or 2 life.) Look at target player's hand. Draw a card.

As an additional cost to cast this spell, sacrifice a creature. Rite of Consumption deals damage equal to the sacrificed creature's power to target player or planeswalker. You gain life equal to the damage dealt this way.

Take an extra turn after this one.

You may pay 1 life and exile a blue card from your hand rather than pay this spell's mana cost. Counter target spell.
