Hey, I was playing against somebody who was using megacolony in standard format where they were attacking with burner ant and kept restanding it by discarding a card. I'm pretty sure they were wrong, but I just want to make sure. Thanks in advance.

Hi, I don't necessarily have a card problem but rather a mechanic in the game.
Here's the scenario: If my vanguard is deleted, then I stride, does the deleted card turn face-up when I stride the g-unit? Would I then be able to activate stride skills like claret sword and chronojet dragon as well as gain their power?

Thank you I appreciate the help

Lizard soldier, viera or beira skill is wrong
Area's skill-
[AUTO](RC) Generation Break 1 (This ability is active if you have one or more face up G units in total on your (VC) or G zone):When your opponent's rear-guard is put into the drop zone due to an effect from one of your cards, choose another of your other rear-guard, it gets 10000 power until end of turn. If it gets 10000 power, return this unit to your deck and shuffle your deck. This ability cannot be used for the rest of that turn.

Actual skill-
[AUTO](RC) Generation Break 1 (This ability is active if you have one or more face up G units in total on your (VC) or G zone):When your opponent's rear-guard is put into the drop zone due to an effect from one of your cards, choose another of your units, and you may have that unit get [Power]+10000 until end of turn. If you do, return this unit to your deck, and shuffle your deck. This ability cannot be used for the rest of that turn.

This card allows you to also target the vanguard rather than just rear-guards
