Keep in mind that, though I was building this for a superfriends deck, the same tech can apply to a sliver deck, a scarecrows/changelings deck, or even the four-color decks coming out later this year (unless you're playing , in which case you'll have to make some larger adjustments)
Each creature you tap while casting this spell pays for or one mana of that creature's color.) One or two target creatures each get +2/+1 until end of turn
While both Secret Rares are beautiful, there's another Lugia card on this list that tops them both
Red in particular in the format tends to be pushing the pace, especially with the Red/White go wide builds, and Red Black reckless aggro, though Red/Blues spell aggro is no slouch either
Development [edit] Planning for Shadowbringers began in May 2017, about one month prior to the release of the preceding expansion, Stormblood , with a three-day "scenario writing camp" involving producer and director Naoki Yoshida and the main scenario writers, Natsuko Ishikawa and Banri Oda
