Volga OTK Direct to Round 2 -
I made a deck before specializing on using Volga's effect to inflict massive damage to your opponent when he takes damage. This time I'm re-working it to use a different ruler, and hopefully this slimmer version will be faster and more efficient.
You will be using whatever options to discard 10 cost cards into the graveyard to be removed with Urthr. If you remove 2 10 costs, she deals 4000 damage to her target, and if you throw that massive damage onto poor Volga it will pass to your opponent.
Flipping to Refrain on the turn you plan to kill allows you to protect volga and urthr from any annoying removal spells shy of Seal of Wind and Light.
