March of the Machine: The Aftermath

Sarkhan, Soul Aflame | Legendary Creature | Human Shaman | Dragon spells you cast cost {1} less to cast. Whenever a Dragon enters the battlefield under your control, you may have Sarkhan, Soul Aflame become a copy of it until end of turn, except its name is Sarkhan, Soul Aflame and it's legendary in addition to its other types. | Eric Wilkerson

Samut, Vizier of Naktamun | Legendary Creature | Human Warrior Cleric | First strike, vigilance, haste Whenever a creature you control deals combat damage to a player, if that creature entered the battlefield this turn, draw a card. | Jarel Threat

Rocco, Street Chef | Legendary Creature | Elf Druid | At the beginning of your end step, each player exiles the top card of their library. Until your next end step, each player may play the card they exiled this way. Whenever a player plays a land from exile or casts a spell from exile, you put a +1/+1 counter on target creature and create a Food token. (It's an artifact with "{2}, {T}, Sacrifice this artifact: You gain 3 life.") | Bram Sels
