The standard manabase is:
If you want 25 lands, then add a treetop. If you want a mountain, exchange the second forest with it and exchange the second foothills with a 4th mire.
With this manabase you have 18 black sources, 18 red sources and 17 green sources. This is definitely enough to cast anger and Lilis. Finks are possible but gets better when you add the 25th land in treetop. This covers everything you might want.
