What is the easiest way to obtain high arcana (not from rewards from monteblanc or w/e, im talkin the harder ways).

I know of 3 methods really.
1.) Bazaar using materials (omg soul of thamasa is so hard to get!)
2.) 5% drop off rare game mobs with the canopic jar.
3.) Steal from espers? (all i have left is ultima and zodiark to get.)

Whats the easiest way? i just need my high arcanas for my tournesol =(
