But hang on - what does 'trading card game' mean, anyway
Warp Warp is a mechanic that is geared towards brewing because it is powerful and creates mini-puzzles of how to get additional value out of a summoning sick creature that only sticks around for your turn
Similarly, if The Soul Stone is already harnessed and becomes a copy of something else, it stays harnessed, though it's very likely that won't be relevant until that copy effect ends
Im not including a lock spell here on purpose to avoid those kinds of combo-y interactions (Dramatic Reversal, Silence, Time Walk)
Simply put, the cards tick all of the boxes for both collectors and competitors
As always, comments and suggestions are welcome
