Basking Broodscale + Reyhan, Last of the Abzan + Thunderous Velocipede

Basking Broodscale

Reyhan, Last of the Abzan

Thunderous Velocipede

How it works

1. Cast Basking Broodscale by paying 1, causing it to enter with a +1/+1 counter due to Thunderous Velocipede.
2. When Basking Broodscale enters, it triggers, creating an 0/1 Eldrazi Spawn creature token that enters with a +1/+1 counter due to Thunderous Velocipede.
3. Activate the Eldrazi Spawn by sacrificing it, adding C.
4. When the Eldrazi Spawn dies, Reyhan triggers, putting at least one +1/+1 counter on Basking Broodscale.
5. Basking Broodscale triggers, creating an 0/1 Eldrazi Spawn creature token that enters with a +1/+1 counter due to Thunderous Velocipede.
6. Repeat from step 3.

This intricate loop transforms a humble entry into an unending cascade of growth and sacrifice. As Basking Broodscale enters the battlefield, the passive stat boost from Thunderous Velocipede instantly primes it with a counter, which triggers the Broodscale to spawn an Eldrazi Spawn token that itself arrives juiced with an extra +1/+1 counter. When you sacrifice that token for mana, Reyhan, Last of the Abzan steps in to redirect its counters right back onto Basking Broodscale, instantly restarting the Broodscale's token-generating trigger.
