Negate any Trap effects that target this card, and if you do, destroy that Trap Card. If this card attacks, your opponent cannot activate any Spell/Trap Cards until the end of the Damage Step. At the end of the Damage Step, if this card attacked and is still on the field: Target 1 Spell/Trap Card your opponent controls; destroy that target.
These are among the most prominent Spell/Trap cards in current meta that are triggered during Battle Phase, to protect monsters on the field and it will be suppressed by Ancient Gear Engineer during its battle phase.
This is the recommended support card for Ancient Gear Engineer. Reason being not only this card boosts it’s attack by 400 every turn, it also grants Ancient Gear Engineer the ability to negate monster effects that it destroys, effectively making it heavily immune to Spell/Trap/Monster Effects during the Battle Phase. And as a bonus, the 400 attack increase will continue every turn, even after this card is removed from the field. However, do take note that monsters’ effects are still able to be activated from the graveyard.

Crowler just dropped its prismatic card on lvl 40 for me
I summoned this card and my opponent was able to activate Floodgate Trap Hole. Not sure if this is a glitch or if this is how it's intended to work but unless Konami addressed this I would suggest don't summon unless you're sure your opponent doesn't have it set.
Engineer is an underappreciated card. Of course w/ no Giant Rat, he's not worth the sacrifice realistically, but I always kept one around my old AG decks as a jnk (just in case). Not like we aren't rocking MASSIVE back field protection cards right now & Crowler's basic Skill = free tribute summon going 2nd.
I'd just stick to sargent electro. Its stronger, doesn't require tribute, doesn't have to attack, doesn't trigger "when this card is destroyed" effects, and stops opponent from playing new card to replace it. Only downside is that it isn't immune to traps, but that means it can be targeted by rare metalmorph.
