Try a few tools to see which one you like best for making a custom trainer card with your favorite pokemon
I mean, considering all the effort you have to go through to get Rainbow Dragon out(who is already a pain to Summon), in addition to a Tuner who is useless outside of 2(well, 3, since This card) cards, you should give the player a decent reward for going to such extremes
While the goal will always be that 0.5 card OTK, itd be foolish not to have a few redundancies built in
Plus, you can earn some beautiful FINAL FANTASY-themed promotional cards to grow your collection while playing the game you love
The rest of the ratios look good, though I would prefer another board wipe or two: board wipes are good because your early turns are spent ramping, not developing a board presence, so a board wipe is a great catchup mechanic before you start dropping your haymakers
