Oh crap.. I was thinking Amped Raptor is strong with galvanic discharge and such energy shenanigans... But then there's the suspend cards are 0 mana value exploit... I think they should do a rules update that no mana value is no mana value rather than 0 mana value - ie cascade would just go past them as no mana value is not less than anything or equal to anything or more than anything and you could not pay 0 with the raptor.. They might need to be still 0 mana value as permanents tho.
Your logic is sound on See the Truth.....it keeps getting better the more they print "_you may cast from exile_" which happens to be almost every set now.
