Rograkh, Son of Rohgahh + Myth Unbound + Blasting Station + Estrid's Invocation

Rograkh, Son of Rohgahh

Myth Unbound

Blasting Station

Estrid's Invocation

How it works

1. Activate Blasting Station by tapping it and sacrificing Rograkh.
2. Choose to have Rograkh return to the command zone from your graveyard.
3. Both copies of Myth Unbound trigger, causing you to draw two cards.
4. Resolve the ability from step 1, dealing 1 damage to any target.
5. Cast Rograkh from the command zone by paying 0 due to the cost reductions from both copies of Myth Unbound.
6. Blasting Station triggers, untapping itself.
7. Repeat.

This clever loop turns zero-mana commander casts into a lethal machine, utilizing Rograkh, Son of Rohgahh as a disposable sacrifice outlet that costs nothing to recast. Myth Unbound does heavy lifting here by both granting essential mana cost reductions so Rograkh can be re-cast for free and replacing every trip to the command zone with fresh card draw. Meanwhile, Estrid's Invocation enters as a clever copy of Myth Unbound to double up on those cost reductions and draw triggers. With Blasting Station providing both the sacrifice outlet to send the kobold away and an untap trigger every time it re-enters, you can repeat the cycle endlessly to ping down your opponents.
