It has a strong proactive gameplan, enough card selection from Ancient Stirrings and Whir of Invention to consistently execute that plan, and two great pieces of protection in Welding Jar and Spellskite, so artifact removal like Abrade and Ancient Grudge is typically inadequate
These cards were printed by manufacturers to check how new frames, colors, foiling, or other technical features would look before a real set released
Add in some removal spells, some card drawing, and some heavy-hitting creatures like Lord of Extinction
Ideally, this has the power of an instant Desert Twister in Dimir colors as if your foe has no hand, they discard what was bounced, but given the casting one spell restriction of the format, this is something that rarely happens here, making this just a discard of their worst card
I hope you enjoyed the read, until next time!
