2. Act 3 bosses are also defeated with an empty deck.
3. 100% more Time Eater!
4. Ascension 20 this time, so we have to remove Ascender's Bane (among other things).
Of course, Ascender's Bane is supposed to be impossible to remove, so this run can't be glitchless.

This long-standing glitch has recently been fixed on the most recent beta release, but I do almost all of my runs on the current non-beta patch, where the glitch is still available.
