If the target permanent is an illegal target when Bahamut's third chapter ability tries to resolve, it won't resolve and none of its effects will happen
Adding a Sorcery clause onto it slows things down even more
Likewise, MDFCs like Valakut Awakening dont make the cut on this list, as you should be playing MDFCs in all of your decks and they dont tend to encroach on deckbuilding slots like actual spells
Sin, Spira's Punishment Squall, SeeD Mercenary These Through the Ages cards are also worth splashing: Winota, Joiner of Forces Bruse Tarl, Boorish Herder Kenrith, the Returned King Kraum, Ludevic's Opus Muldrotha, the Gravetide Mythics As with rares, the mythics youll want to splash are basically just bombs
This is fantastic, particularly if you made the agonising decision to use a couple of powerful cards as Ink earlier in the game
If you have a ramped inkwell and can land Philoctetes in your revamped hand, all the better
