Various issues with Copycat

[x] Copycat doesn't act correctly after using Bump (https://github.com/TerryCavanagh/diceydungeons.com/issues/1540)
[ ] Doesn't seem to take substitutions into account (https://github.com/TerryCavanagh/diceydungeons.com/issues/1574)
[ ] Copycat can trigger the Precious Egg achievement (https://github.com/TerryCavanagh/diceydungeons.com/issues/1602)
[x] Berlin Key can cause Copycat to softlock (https://github.com/TerryCavanagh/diceydungeons.com/issues/1799)
[x] When facing Jester, size 2 cards can become size 1, which looks very weird (this is an easier fix than it sounds like) (https://github.com/TerryCavanagh/diceydungeons.com/issues/2003)
