I love the complexity of this game. It makes you think. It challenges you to a new way of looking at cards each and every time you draw a ruleset and a mana cap. That's a unique mechanic, that is endlessly fun, and endlessly rogue-like.
All things considered, the game is exceptionally well designed and balanced, but I feel as though, even though - we have a highly intelligent player base (which is often the most dangerous thing in gaming) - sometimes the game just needs to "dumb it down" a little.
There's a certain elegance in the lower leagues which does this through the fact that there is not a complex interplay of multiple abilities, and as a player progresses in leagues this builds - but the advent of things such as battle helpers remove this feeling of "explore a new strategy" because many will never understand why the strategy works, only that they reproduced a team and got a certain outcome.
I always enjoy playing outlandish teams that are surely destined to not succeed, but because, through the fact that the "meta" expects one thing, I can sometimes win in unexpected and hilarious ways.
