How to Use Food Chain

I had been aiming for this situation, but I encountered a brilliant counter, so I'd like to share the details.

I summoned Bladefly and fulfilled the conditions of Manasurge to use Food Chain.

A unit I've never used before was summoned. It's delightful to have a unit with Blitz.

After destroying all of the opponent's units, two untouched 6-mana units remained.

Bifurcating Curse destroyed all units. This was an unexpected setback because, naturally, Bladefly shares the same mana, becoming a fatal weakness.

Resisting with Oni.

It's a complete defeat with End Times.
Feeling disheartened, I decided to concede at this point.

Without counters like the one encountered in this match, Food Chain is exceptionally powerful. It was a very instructive game.
