If there is a mistake or some clarification is needed, this is the time to let us know
Summon: Fenrir is an ideal ramp spell for Saga Tribal because it has similar utility to Rampant Growth (which is a top staple) at I, while its other abilities are less relevant, but also useful
I also looked for some expensive sagas that I wouldnt normally include in a deck, like The World Spell, since theres a chance youll get to play them for free thanks to Tom
