I think your concerns are valid

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

Fortunately for you and unfortunately for your opponents, because Blightsteel Colossus is indestructible, if they dont have an exile card, a creature 11 power or greater, or a horde of creature tokens with a total power of exactly 11, the game is done
