I was experimenting with leveraging his first ability for discard and card draw, went with:
Critters:
- Misc random Monster
- Misc random Monster 02
Spells:
- River, for CC and support destruction
- Reason, since it is useful and has Aftermath
- Consign, CC and has Aftermath
- Misc CC spell
- Misc CC spell
Supports:
- Storm the Vault, for lots of mana
- Azcanta, for filtering the Aftermath cards and free spells
- Sphinx’s Tutelage, because of the immense card draw
I went with a build for his third ability.
Creatures:
Timestream Navigator
Mizzium Meddler
Spells:
Desert of the Mindful
Perilous Voyage
Expel from Orazca
River’s Rebuke
Talent of the Telepath
Supports:
Arch of Orazca
Search for Azcanta
Dowsing Dagger
Pretty simple, use bounce to live, hit 3rd ability for tokens that activate loyalty, when you have City’s Blessing, you can churn out tokens from 2nd and 3rd ability and get extra swaps with Timestream Navigator so you can gobble up extra loyalty or hit off color activations while still getting mana to cast stuff.
