While we wouldnt have the full block until 2013, Return to Ravnica brought powerful new tools (Abrupt Decay, Sphinxs Revelation, Cyclonic Rift, Rest in Peace, Dreadbore) and one unassuming but eventually problematic megaguildmage/one-mana planeswalker in Deathrite Shaman
Creatures (14) Lands (22) Spells (23) 1 Fireball 4 Lightning Bolt 1 Hymn to Tourach 3 Necropotence 4 Dark Ritual 3 Drain Life 1 Black Vise 2 Shatter 3 Incinerate 1 Zuran Orb Sideboard Look, the mana wasnt great in those days
We have not seen that before, but it could prove to be a bit crippling
Then flash this back for another one for two more mana, get it and run it all up and down the block
Do we really need a good reason why Starting Town became an instant-include
Artifact and Creature Sacrifice is one of the weakest archetypes since you need a lot of high-rarity cards to make it worth playing
