My current Magic deck is W/R and focuses on enchant creature spells. In addition to boosting creatures I control (mainly weenies so I can get plenty out quickly), I have two Celestial Ancients in my deck (3WW, Flying 3/3, whenever an enchantment is played put a +1/+1 counter on each creature you control...so, if I have both out, each time I play an enchant creature each of my creatures gets a +2/+2 counter ). If this tactic doesn't completely own the enemy, I have Brion Stoutarm also (2RW, 4/4, recovers X life whenever it deals X damage, R+tap+sacrifice another creature to deal damage equal to that creature's power to target creature or player then gain that much back with his amazing Lifelink ability) to toss, for example, 15/15 Celestial Ancients + other monsters at my enemies.
...ftw.
I always loved drafting Brion, even though giants were weak in the format. I sometimes play standard with Mono Red Elementals. Basically run smoke braider, banquet, Simian Spirit Guide (mana accel for turn one braider or banquet), then beat down with Nova chaser and burn spells.
