During your End Phase: Special Summon 1 "Engine Token" (Machine-Type/EARTH/Level 1/ATK 200/DEF 200) in Attack Position. Once per turn: You can have this card gain 1000 ATK until the End Phase. During the End Phase, if this effect of this card was used: Destroy this card.
Generates a token in ATK position during your End Phase, which makes you vulnerable to opponent’s attacks.
Destroys itself if it has used the effect of increasing 1000 ATK for that turn.
You can also consider using Jinzo together to form a Machine-type deck, but you may want to consider using less Traps in your Deck.
You can also use Treacherous Trap Hole to destroy your token and 1 of your opponent’s monster (or just destroy 2 of your opponent’s monster if they had multiple monsters).
Since the token will leave you vulnerable to opponent’s attack, you can use Escalation of the Monarch during your opponent’s turn to tribute that token, to summon B.E.S monsters. These monsters will obtain counters which makes them harder to be destroyed by battle.
Since Fiendish Engine Ω is a Machine-type monster, it can be supported by Heavy Mech Support Platform, which can be equipped to prevent Fiendish Engine Ω from destroying itself. Enemy Controller and Super Rush Headlong are used as generic protection techs for both Fiendish Engine Ω and the token. Gravity Blaster, Rare Metalmorph and Pulse Mines are good tech cards for Machine-type monsters with Gravity Blaster increasing the equipped Machine-type monster’s ATK every turn, and negates monster effects from the monster destroyed by battle via the equipped Machine-type monster, Rare Metalmorph negates 1 spell that targets the Machine-type monster 1 time, and also increases its ATK. Pulse Mines can turn all opponent’s monsters that was or would-be Normal / Special Summoned, into Defense position, for that turn.
