mtg pact cards Grave Whenever a creature you control is put into a graveyard from the battlefield Magic: The Gathering Eldritch Pact

Combine these effects with the huge amount of cards with low converted mana costs and I can already see this set having a huge effect in many of Magic The Gatherings most popular formats especially Pioneer, where Im already brewing a Toxic Selesnya deck

Hedron Detonator is another Reckless Fireweaver variant that can turn artifact loops into wins, and Pain Distributor punishes excessive Treasure use by your opponents, which is weird considering Sardian Avenger was printed not that long ago

It synergizes with strategies revolving around tokens, lands, and even copying creatures, and can fit into just about any green deck

Vigilance is missing on purpose because it seemed odd to grant the ability when it already had the ability to untap itself
