Post-rot Klawf ex bankrupts opponent

Spirit Mask is Rocky Chestplate: "the Fighting-type Pokémon this card is attached to takes 30 less damage from opponent's Pokémon's Attacks" (that's what it does)
Krabby is Klawf ex: a basic Fighting-type Pokémon with 220 HP and this ability:

Ability - Great Scissor

If this Pokémon is in the Active Spot and is damaged by an opponent's attack (even if it is Knocked Out), discard an energy from the attacking Pokémon.

It has this attack: 

FCC - Falling

Flip a coin. If heads, this attack does 80 more damage.

Get Goodra into the active spot as soon as possible, so that your opponent discards roughly half of the energy they are trying to get into play. Then, send in Klawf ex.

With Lake Acuity (Lost Origin) in play, and 1 V Guard Energy (Silver Tempest) attached (+1 fighting energy), and a Rocky Chestplate (see start of description) attached, Klawf takes 80 less damage from Pokémon V. With this damage resistance, every time Klawf ex takes damage, it is reduced by 80, and the attacking Pokémon loses an energy.

Because Klawf ex is a fighting type, he is a nice counter for Ampharos ex, Zeroara VSTAR/VMAX, and Magnezone ex.

Crushing Hammer because more energy discarding is nice.

After your opponent has run out (or is very low on) energy, use Gyarados to annhilate their deck.

This is a weird deck, and I know it won't work too well, but the main weakness it has is to Ordinary Rod (Sword & Shield), which is luckily about to be rotated out of format. And no one plays Klara. At least, not many people do.

Any advice or additional energy discarding ideas? Put them in the comments below! But remember, this is post rotation, so only cards with E or F at the bottom left are allowed.
