- This card can be searched by "Dogu", "Single Purchase", "Temple of the Kings", "Number 29: Mannequin Cat", "Rescue Ferret", "Transmodify", "Chaos Zone", "Machina Armored Unit", "Qliphort Genius" and "Psychic Shockwave".
- One of the biggest virtues of "Timeater" is that without a Main Phase 1, your opponent normally can't Summon and then attack, so you usually have a turn to deal with whatever your opponent Summons in the way of "Timeater".
- Use cards like "Metalmorph", "Blackwing - Gale the Whirlwind" and "Riryoku" to capitalize off the fact that "Timeater" almost always has the opportunity to attack a monster before the monster can attack it.
- "Timeater" can also offer a strange warding to monsters that need time to work, like "Stealth Bird" or "Swarm of Locusts", by virtue of keeping your opponent from having usable monsters during their Battle Phase.
- Combine with "Terminal World" to skip both Main Phases.
- Combine this card with "Thunder of Ruler" and/or "Frozen Soul" to skip your opponent's turn. If your opponent cannot enter their Battle Phase, then they cannot enter their Main Phase 2 either, essentially skipping their turn when "Timeater's" effect is also applied. "Great Long Nose" offers a repeatable, but less consistent, means of achieving the same outcome, due to the aforementioned monster requiring a Tribute under normal circumstances to be summoned.
- Equip this card with cards like "United We Stand" or "Fighting Spirit" to give this card more opportunities to activate its effect.
