Card Tips:Old Entity Cthugua
- You can also Special Summon this card with "Forbidden Trapezohedron".
- You can revive this card with "Rekindling".
- Doing so can give you a second Level 4 Monster for an Xyz Summon, which will allow you to draw a card.
- This card's first effect is effective against "Evilswarms", as the Deck runs many Rank 4 monsters.
- If you control this card, you can use "Super Polymerization" to fuse it with your opponent's Synchro or Xyz Monster into "Elder Entity Norden", deriving them of a monster and allowing you to draw a card via this card's effect. Then, you can revive this card with the effect of "Norden". Alternatively, if this card is in your Graveyard, you can use "Instant Fusion" to summon "Norden", and use "Norden's" effect to revive this card. Overlay both this card and "Norden" into a Rank 4 Xyz Monster, which will allow you to draw another card by this card's effect.
- You can take advantage of this card being an Xyz Material by following up the above combo with "Black and White Wave", letting you draw a third card and removing another problematic card belonging to the opponent.
- If the Xyz Monster you summon with this combo is "Outer Entity Nyarla", you can then use it as an Xyz Material to Xyz Summon "Outer Entity Azathot". This card, "Norden", and "Nyarla" being attached to "Azathoth" will allow "Azathoth" to use its detach effect to destroy all cards your opponent controls.
- This card is very easily Summoned in a Baby Raccoon Deck. You can use "Valerifawn, Mystical Beast of the Forest's" effect, which will Special Summon a Level 2 Beast-Type monster, and since "Valerifawn" is a Level 2 Tuner, you can immediately Synchro Summon this card.
