I like cards that do interesting things and that have nice art. Therefore Banding and a plethora of COK Block cards. All basic
lands are snow lands and damage is on the stack.

I generally don't like broken cards, so certain cards have custom errata on them. Since I double sleeve all of my cards, I sharpie
errata on the inner sleeve. So for example Umezawa's Jitte only gives you one counter per swing, or Through the Breach puts a
non-Emrakul creature into play, Scryb Ranger no longer has protection from Blue, etc.

Anything that Magic players hate is generally a good idea, so I've found that custom errata and cards like Bronze Tablet or
Banding cards make the game more interesting because it makes everyone else angry. Generally what Magic players want is for the
game to be dumbed down and less interactive so they can have EZMode wins, ie they hate fun, fair, interactive Magic as Richard
Garfield intended. This is why the elegant Shroud was replaced with the non-interactive Hexproof. This is why Magic players loved
Mirrodin block but hated Kamigawa.

The polar opposite of something like Carnage Tyrant is Dash Hopes. Carnage Tyrant is impossible to interact with, and Dash Hopes
has interaction built into it. Dash Hopes is a more well designed card.
