Decks like Krenko, Mob BossKrenko, Mob Boss, Isshin, Two Heavens as OneIsshin, Two Heavens as One, and Etali, Primal StormEtali, Primal Storm would absolutely love this card, as it enables them to do "their thing" the turn they come down
Wiping out all creatures for 2 mana is massive
Im always wary of Hill Giants, but Sazh has some great upsides, and I expect it to be a solid card in any deck that plays it
All the exhaust abilities seem powerful, and the ability to activate them on the turn Loot comes down is great, provided you have a spare mana
The ability to replay lands from the graveyard in huge chunks has serious connotations, especially in Timeless with fetches
Its also not lost on me that a blue artifact looking to yoink spells from your opponent probably doesnt want to target the other blue player - for the risk of running into a counterspell which will be a pointless hit to get unless youre activating Synthesis Pod in response to an already ongoing stack war
