Illusionist's Gambit

Cast this spell only during the declare blockers step on an opponent's turn.
Remove all attacking creatures from combat and untap them. After this phase, there is an additional combat phase. Each of those creatures attacks that combat if able. They can't attack you or planeswalkers you control that combat.

The Caretaker

Vigilance, ward {2}
At the beginning of each end step, if you faced a dilemma this turn, target opponent exiles cards from the top of their library until they exile a nonland card. You may cast that card without paying its mana cost. (You face a dilemma as you choose one or more modes for a spell or ability.)

Scotty, Miracle Worker

During your main phase, each card in your graveyard has beam me up. The beam me up cost is equal to that spell's mana cost. Scotty can't be beamed up to cast a spell this way. (Only instant and sorcery spells can be cast this way. You may cast a card from your graveyard for its beam me up cost if you also return another creature you control to its owner's hand. Then exile that spell.)

Riku of Many Paths

Whenever you cast a modal spell, choose up to X, where X is the number of times you chose a mode for that spell —
• Exile the top card of your library. Until the end of your next turn, you may play it.
• Put a +1/+1 counter on Riku. It gains trample until end of turn.
• Create a 1/1 blue Bird creature token with flying.

Phyrexian Tower

{T}: Add {C}.
{T}, Sacrifice a creature: Add {B}{B}.

"Surely, I have made my meaning plain. I mean to avenge myself upon you, Admiral."

Khan, Vengeful Heart

When Khan enters, you may sacrifice another creature or artifact. If you do, draw two cards.
You may cast this card from exile.

Hull Breach // Hull Breach

Hull Breach

Choose one —
• Destroy target artifact.
• Destroy target enchantment.
• Destroy target artifact and target enchantment.

Herald's Horn

As this artifact enters, choose a creature type.
Creature spells you cast of the chosen type cost {1} less to cast.
At the beginning of your upkeep, look at the top card of your library. If it's a creature card of the chosen type, you may reveal it and put it into your hand.

Dr. Leonard "Bones" McCoy // Dr. Leonard "Bones" McCoy

Dr. Leonard "Bones" McCoy

Flash
When Dr. McCoy enters, choose one —
• Return target non-Doctor permanent card from your graveyard to your hand.
• Choose up to one other target creature. When it dies this turn, return that card to the battlefield under its owner's control with a +1/+1 counter on it at the beginning of the next end step.

Commander Spock

Strange new worlds — Whenever Commander Spock enters or attacks, reveal the top card of your library. You may cast that card without paying its mana cost if that spell's mana value is equal to or less than the number of differently named lands you control. If it's a land card, you may put it onto the battlefield tapped. If that card is still on top of your library, draw a card.
