Which magic deck is better?

number 2 try running 22-23 lands at minium i think number 2 is a nice build with the umbras and beastmaster ascension then with the token gain they get +5+5 you run over your oppenet then the garruk i would suggest getting more of those to untap your lands you could go with out the pelakka wurms to add something bloodbraid elf which will have a nice cascade since a majority of the things in your deck you can cascade into
