The three main creatures youre going to be exiling now are: Eternal Scourge Misthollow Griffitn Squee, the Immortal All three of these creatures let you cast them from exile, and since youre always netting one more mana per activation, you can set yourself up with infinite mana
That's pretty flexible and adds another enchantment removal spell to my spots as well as playing save the team
This allows you to be aggressive with your attacks and untap them to make sure you have blockers and mana up for interaction since your mana rocks will untap as well
Theres no theme or reasoning behind any of them, I just think theyre funny and low quality enough to earn recognition
decks running cards like Return from the Different Dimension that bring back banished creatures
Having an Abrupt Decay in hand or in deck with more removal, it might be better to proactively take that pesky planeswalker, or counterspell, or Path to Exile, or any non creature card
