it's a nice new idea to play exodia , but I don't see a point of it really
Strong Back may be yet another creature gets increasingly large for each aura and equipment in play/attached to it/in your favorite sandwich, but its also a huge cost reducer
and the trading card game that grew out of it, eventually going on to sell over 22 billion cards (and counting)
A deck with lots of 4-5 attack fliers work quite well with many of the battle cards, especially when you can target the player without pillowfort or flying effects as the designated defender
(They cost less to cast for each artifact you control.) +2: Tezzeret deals X damage to each opponent, where X is the number of artifacts you control
Higher Levels/Ranks have a wider range of card totals that can apply to them, increasing the odds of a Fusion and two Xyz combination residing in the Extra Deck
