I'm not the only on to ever think things up - but Blue is just way too strong...
It is the only color that can inherently say "no" to something another player wants to do... That can easily ruin the game for everyone...
I used to play blue.. I'd power sink with psychic venoms on your lands... I'd copy artifact, then destroy yours... Heck, I'd go perpetual, and not look back...
but then the game isn't a game - it's more of a one-sided show...
i like players being able to play their decks, and see their combos, and ideas work, I don't want to say no, just because it would kill me... I'll do my dangedest to stay alive - but would rather shake someone's hand and congratulate them on the win, then not let them play their creation...
I run a strong utility control deck - with no blue in it, that I built to show people, there is control outside of blue... and the cards are more fun to use... and opponents like seeing them more also... It's just better overall that way...
and a game... not a show...
(But Homestar summed a lot of it up really well...)
BH - threads throughout the CPA have some ideas I posted with blue involved... you'd probably agree those combos are downright wrong... you don't want to know what else is in this head of mine... Heck - one of them made an infinite ring of ma'ruf, simply scary...
