Iymrith, Desert Doom | Legendary Creature | Dragon | Flying Iymrith, Desert Doom has ward {4} as long as it's untapped. Whenever Iymrith deals combat damage to a player, draw a card. Then if you have fewer than three cards in hand, draw cards equal to the difference. | Wisnu Tan

Demilich | Creature | Skeleton Wizard | This spell costs {U} less to cast for each instant and sorcery spell you've cast this turn. Whenever Demilich attacks, exile up to one target instant or sorcery card from your graveyard. Copy it. You may cast the copy. You may cast Demilich from your graveyard by exiling four instant and/or sorcery cards from your graveyard in addition to paying its other costs. | Daniel Zrom

Xanathar, Guild Kingpin | Legendary Creature | Beholder | At the beginning of your upkeep, choose target opponent. Until end of turn, that player can't cast spells, you may look at the top card of their library any time, you may play the top card of their library, and you may spend mana as though it were mana of any color to cast spells this way. | Kieran Yanner

Tiamat | Legendary Creature | Dragon God | Flying When Tiamat enters the battlefield, if you cast it, search your library for up to five Dragon cards not named Tiamat that each have different names, reveal them, put them into your hand, then shuffle. | Chris Rahn
