Gandalf the White will double such cards' triggered abilities based on entering or leaving the battlefield, which can generate tremendous advantage in the right decks
Im excited to officially reveal not only MTGs Street Fighter crossover cards, but ALL 41 of the cards in the February Secret Lair Superdrop
Whenever you draw your second card each turn with Thopter Fabricator under your control, you create a 1/1 colorless Thopter artifact creature token with flying
6 Palafin EX Zero To Hero Palafin EX has a fantastic ability that lets it come into play directly from the Deck
And, with white giving access to recursion likeSun Titan orSevinnes Reclamation for cards with a low mana cost, you could bounce it back from the graveyard
None of that directly involves Zirda, but I feel like it's the direction you'll find yourself in if you build a deck with only permanents that have activated abilities
