Fun Fact: If you combine Iron Legacy and Plague Rat, you can build an unstoppable damage machine of doom. Use the two Demoralising Presences, Galvanised and two copies of Shadowy Ambush as your H starting ongoings (as Iron Legacy) and fill the rest of the deck with cards that hit all heroes for 2 or more damage:
- Vicious Onslaught x2 - 8 hits for 5 damage each.
- Ravage x2: 4 hits for 5 damage each.
- Rule From The Front x2: 5 hits of 7 damage each.
- Flying Assault x3: 4 hits of 7 damage each.
- Sun's Fury x2: 5 hits of 5 damage each.
- Mass Overheating x2: 5 hits of 5 damage each.
- Hasten Doom x4: 5 hits of 5 damage each (plus a card play).
- Devious Disruption x2: 5 hits of 6 damage each.
- "Consider The Price of Victory: 5 hits of 5 damage each.
The first card play triggers n x 2 card plays, where n is the number of hits it inflicts; each further card then triggers n x 2 more card plays. Now this can only go on until the deck runs out, but the deck will be run out on the first instance of damage from each card; then the 19th card will play that card (n x 2) - 1 more times, then the 18th card will play (n x 2) - 1 more 19th cards... Oh, and then at the end of the round Iron Legacy deals everyone 6 damage and triggered this ten more times.
The total number of hits inflicted by 20th cards will be something like 1.2 x 10^20 (or 100,000,000,000,000,000,000); each hit is for about 5 damage, so that's 6 x 10^20, and the chain is done 11 times, so 6.6 x 10^21.
I do not plan to use this deck. Ever.
