a grand list of them includes: Sabotender (the only non-bird common with landfall) Chocobo Racetrack (slow bird token-maker that does nothing the turn you play it) Ride the Shoopuf (card is actually pretty good, no complaints) Tifa Lockhart (the one-shot dream is cool but very hard to pull off in Limited) RG isnt especially well supported in Final Fantasy
