I have two simple card strategies.
1) Endless wurm (for urza's saga) +
Rancor(urza's legacy) = 11/9 trampler for 3 and 3green
The idea is you get your wurm out and rancor it (+2/0 and trample
fo ra green) the best creature enchantment ever! and keep sacrificing
rancor because you need to sac. an enchantment every upkeep, but rancor just
pops back into your hand, then you replay it on the wurm.
Next
Tethered Griffin(urza's destiny) +
Rancor = a 4/3 fyler with trample for a white and a green
with a lotus petal you could have it out turn 1 oww... Griffin needs an
enchantment in play but cost only 1 and is a 2/3 flyer so play rancor on
it.
