Some kinda-broken combos.
Clearing Border Village in one turn:
Grujah buys a Border Village.
... gaining a Torturer.
... Grujah reveals a <Morgrim>
...... gaining a Border Villliage instead. (this goes to discard, <Morgrim gets returned>)
.........gaining a Torturer.
.........Grujah reveals a <Morgrim>
.............gaining a Border Villliage instead.
Etc.
Even worse with Cache. You need a Trader and two <Morgrim>s in hand.
Buy a Cache.
Get 2 coppers, Reveal trader, make em both Silvers.
Reveal <Morgrim> on one silver to get a 4, than again to get a non-Cache $5. This goes to discard, <Morgrim>s back in hand.
You reveal two times again to turn Silver into Cache. Cache goes to discard, <Morgrim>s back in hand. Two coppers on a way.
Repeat!
Similar IGG thing could be made.
