Beckett Mariner, Impetuous Ensign

Lifelink Whenever Brad Boimler becomes tapped, until end of turn, if one or more counters would be put on a permanent you control, that many plus one of each of those kinds of counters are put on that permanent instead.

If you gaining life causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time. Whenever you gain life, put a +1/+1 counter on Dr. Crusher.

Choose one — • Stun — Tap target creature and put a stun counter on it. (If a permanent with a stun counter would become untapped, remove one from it instead.) • Kill — This spell deals 3 damage to target attacking creature.

Choose one — • Interfere — Counter target spell unless its controller pays 3. • Observe — Tap up to one target creature and put a stun counter on it. Draw a card. (If a permanent with a stun counter would become untapped, remove one from it instead.)

Kicker 1U (You may pay an additional 1U as you cast this spell.) Counter target spell with mana value 2 or less. If this spell was kicked, instead counter target spell.

Federation — When Hoshi Sato enters, look at the top X cards of your library, where X is the number of creature types among non-Borg creatures you control. Put one of them into your hand and the rest on the bottom of your library in a random order.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.) I — Each opponent sacrifices a nontoken creature of their choice. II — Investigate. (Create a Clue token. It's an artifact with "2, Sacrifice this token: Draw a card.") III — You may sacrifice an artifact or creature. If you do, create two 2/2 black Romulan creature tokens.

Lifelink When this creature enters, look at target opponent's hand. You may choose a nonland card from it. If you do, that player exiles that card, then draws a card.
