Support

For the full Aluren experience see Caleb Gannon's Powered Synergy Cube where the creature curve basically ends at 3 cmc.

Convoke also gives a nice stormy feeling and a payoff for casting many creatures.

Flurry and Celebration could be nice support mechanics that reward you for your second spell.

Also the storing mana in the form of Treasure Tokens is great for a splashy turn and within s identity, e.g. Rain of Riches.
