Flying, vigilance, deathtouch, lifelink

At the beginning of your end step, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

When Breya, Etherium Shaper enters the battlefield, create two 1/1 blue Thopter artifact creature tokens with flying.

{2}, Sacrifice two artifacts: Choose one —

• Breya deals 3 damage to target player or planeswalker.

• Target creature gets -4/-4 until end of turn.

• You gain 5 life.

At the beginning of your end step, draw a card. Each player may put a land card from their hand onto the battlefield, then each opponent who didn’t draws a card.

Vigilance, haste

As Saskia the Unyielding enters the battlefield, choose a player.

Whenever a creature you control deals combat damage to a player, it deals that much damage to the chosen player.

Trample

Whenever Yidris, Maelstrom Wielder deals combat damage to a player, as you cast spells from your hand this turn, they gain cascade. (When you cast the spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom of your library in a random order.)
