If you manage to remove Arc Trail from the graveyard somehow before the cleanup step (Relic of Progenitus can help with that), Tarmo will shrink down to 0/1 immediately and hit the grave upon the nearest SBA check
Deathrite is a pretty consistent source of mana in these decks with a lot of discard and loot effects on the go
There's never been a better time to learn how to play, and the set's Welcome Decks are one of the best ways to start slinging spells and webs
It may be cast at a time you normally wouldn't be able to cast a creature spell, but other restrictions (such as "Cast this card only from your graveyard") are enforced
It ramps your mana, gains you life, draws you cards and, importantly for this deck gives you +1/+1 counters
Maybe well see a wildly transformed mega-Jafar like Ursula in the Illumineers Quest: Deep Trouble
