Here's my question: What's the fastest completely unupped poison deck, in terms of ttw?
If you -only- want Poison damage (and the physical from Arsenic), it'd still be good ol'
speed poison.
Upped it's easier to speed up by adding Arsenics and Animate Weapons, but unupped you'd need Novas for Flying Weapon.
It's quite possible for a Poison+Deathstalker deck to become faster, provided it draws Nightfall soon enough and has Arsenics. However, as you know, they need to continually hit. Since TTW tests are ran against Elders, you'd have to establish rules for this specific test run.
