Eladamris Call has the added flexibility of letting you pay over the course of two turns (two now for the Call, and then two more when you untap and want to drop your Devoted Druid)
Because of this, even if you play it on turn 3, it is natural for the power to be 5 or 6 the next turn, and because the mana has increased, you can deploy creatures with high power, making it easier to crew, or it can crush the opening created by paying for a heavy crew, which greatly enhances the perfection of the card's strength
Saruman is known for his machinations against Rohan, and his sowing the seeds of animosity between the lesser-tribes of the region against the house of Theoden, which feels super blue-black
And that spell cast from your yard counts towards the Demilichs cost reduction
Super Shredder will be just as effective at tearing through your opponents' cards as the office appliance with which he shares his name (although you absolutely shouldn't physically shred any cards as you send them to the graveyard)
