The Final Boss - 2nd Chapter - Plants and Zombies

In the midst of his panic state, the shards had been readied again. With that happening, a new card landed in his hand, a fire card that he was unfamiliar with.

THE FIRE BLADE OATH

1+Fire Mana+Fire Mana

[Quickening Spell]

Produce eight Fire Mana.

You can only cast one more spell this turn.

Mana: Fire

It should be a good card, if it was in his hand when he had Dragon Tempest, but for now, its only use was just as a mana source.

"I'm setting The Fire Blade Oath as a mana source."

Six shards on his side, with only three illusion cards to protect him. Of course only one of it that he could cast, but Reap What was Sowed was still missing one mana source, while his best option, Harvest the Soil would make his plan to get Abrasion from his used pile too clear, making Anzu alerted with it, and would give her time to prepare a counter to it.

REAP WHAT WAS SOWED

5+Wood Mana+Wood Mana
