I quite like the first three, but Mysidian Elder and Queen Brahne are pretty weak cards
The reason this card is so strong right now is similar to why Pikachu ex was so good early on during the Genetic Apex metagame
With access to all of these possibilities at your fingertips for a mere 3 mana creature, Imperial Recruiter is a borderline staple for most decks that can play it even if they have access to colors with better tutors
You can tap any untapped creature or artifact you control to pay a waterbend cost, even one you haven't controlled continuously since the beginning of your most recent turn
(1) If you control a Tuner: Special Summon 1 Tuner from your hand, Deck, or GY, also you cannot Special Summon from the Extra Deck for the rest of this turn after this card resolves, except Synchro Monsters
It will contain 295 cards: 217 cards in its main set and 78 secret rares
