Courser actually probably won't add much value since your hand will be full of lands from all the land ramp spells.  I'd drop for harmonize or explore.

Chameleon Colossus is an option too!

Taurean Mauler?  Gets huge fast and counts as a dragon because it's a changeling.

Regrowth over eternal witness - you need the mana more than the body.

Scourge of the throne might not be worth the dollars, maybe zirilan, feldon, hellkite tyrant, or kiki-jiki instead?


Stormbreath dragon isn't terrible either for the haste and protection from white.

Flameblast Dragon is removal too.

Maybe make room for earthquake or similar?  You'll have lots of mana and you can get around pillow forts as well as clear out creatures.

I'd say extraplanar lens isn't worth it - applies to your opponent's lands as well, doesn't apply to your non-basics, easily removed, and expensive dollar-wise.

Search for tomorrow, sakura tribe elder, or yavimaya elder instead maybe?

Also myriad landscape could replace opal palace and add additional ramp.

There's blighted woodland too.

burgeoning is arguably better than exploration and 1/3rd the cost!

could do sword of the animist for ramp too?

mana: harrow, nissa's pilgrimage
gruul signet and fellwar stone over some of the 3 cost rocks

seething song to get things going quicker




opal palace doesn't seem worth it

other stuff:
doubling season and/or parallel lives if you're making a lot of tokens


that enchantment that trips when opponent's control i think 4 creatures?  that lets you tutor onto battlefield 2 creatures

i'd say lands to protect your commander (homeward path, strip mine (for things that turn it into lands), sac outlet lands (for being turned into garbage creatures) but commander doesn't seem essential to your strategy

Harrow over explosive vegatation maybe?

Thoughts - I'd find room for Krosan Grip and Terastodon.
Oracle of Mul Daya >: Courser.
Fertilid is kind of weak.
