Better combo would be Displace on Greenwarden and Angel of Invention with Tamiyo's emblem.

Why not both? I feel like we have the beginnings of a combo deck here. Could also include:
Call the Gatewatch to find Tamiyo
Ajani Unyielding whose ultimate can help Tamiyo get her's off
Oath of Gideon for more starting loyalty = faster ultimate
Architect of the Untamed to use all that whale energy

Yeah man nothing like a 20 card combo that requires your opponent to have no removal and/or counterspells

Works every time babs.

Fo sho! That's the best kind of deck.

Haha

It only took two tries and my opponent getting mana screwed to pull off the Aethertide Whale + Tamiyo, Field Researcher combo! I didn't have Valor, but I did have a Bristling Hydra to use the energy (though the game was pretty much over anyway).
