As an additional cost to cast this spell, pay {4} or sacrifice a creature.

When Leafmantle Dryad enters, if you control a legendary creature, you may search your library for a basic land card and put it onto the battlefield tapped, then shuffle.

Return each nonland permanent you don't control to its owner's hand.
Coalesce {6}{U}{U}{U} (You may cast this from your graveyard for {6}{U}{U}{U}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

Put a +1/+1 counter on target creature. (Then exile this card. You may cast the creature later from exile.)

All creatures get -2/-2 until end of turn.

Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)
Whenever Flamecloaked Artisan attacks, exile the top card of your library. If it's a nonland card with mana value less than Flamecloaked Artisan's power, you may cast it this turn, and you may cast it as though it had flash.

Draw a card. Then you may cast an instant spell with mana value 2 or less from your hand without paying its mana cost.

Whenever you cast a spell, if you cast it for an alternative cost or cast it from anywhere other than your hand, create two 1/1 blue Elemental creature tokens with flying. (Reconstruct and rhapsody are alternative costs, hybrid costs are not.)

Manifest the top card of your library and the bottom card of your library. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

Whenever Siltbottom Freebooters attacks, target Pirate gains menace until end of turn.

Voracious 1 (As this enters, you may sacrifice an artifact or creature. If you do, it enters with a +1/+1 counter on it.)

Target creature gets -X/-X until end of turn, where X is the number of enchantments you control.

Pressure {3}{U}{B} (You may cast this spell for its pressure cost if there are seven or more cards in your graveyard.)
Slipstream (This creature can't be blocked as long as only creatures with slipstream are attacking.)
{U}{B}, Reveal Cuxuri Beckoner from your hand: Target player mills two cards.

Protection from mana values lower than Ironwood Elemental's power (This permanent can't be blocked, targeted, dealt damage, or enchanted by anything with mana value lower than this creature's power.)
Ironwood Elemental's power and toughness are each equal to the number of creatures you control.

Look at the top six cards of your library. Put up to two creature cards with total mana value 4 or less from among them onto the battlefield and the rest on the bottom of your library in any order.
Ferocious — If you control a creature with power 4 or greater, put a +1/+1 counter on each creature you control.

You may exert Outlands Bodyguard as it attacks. When you do, it must be blocked this turn if able. (An exerted creature won't untap during your next untap step.)

Whenever you cast a white spell, you may have Heraldry become an Angel creature in addition to its other types or stop being a creature.

Flying
Whenever Hecatomb Haunter enters or attacks, up to one other target nonland permanent phases out. (Treat it and anything attached to it as though they don't exist until its controller's next turn.)
