During the Main Phase of the turn you Normal Summon it, Ritual Beast Tamer Elder allows you to Normal Summon 1 “Ritual Beast” monster in addition to your Normal Summon/Set. Use Elder’s effect to Normal Summon a “Spiritual Beast” monster and then Special Summon Ritual Beast Ulti-Apelio, Ulti-Cannahawk or Ulti-Pettlephin from your Extra Deck.
Once per turn, Spiritual Beast Cannahawk allows you to banish 1 “Ritual Beast” card from your Deck. The banished card will be added to your hand during your 2nd Standby Phase after the activation of this effect, but, thanks to Ritual Beast Return and your “Ritual Beast” Fusion Monsters, you will have access to it right away.
Hopefully, this doesn’t sound too complicated because this is just the basis for a particular play you can make with Ritual Beast Ulti-Cannahawk. What you need to know is that Cannahawk’s effect can be used once again when it’s Special Summoned, so you will be able to banish another “Ritual Beast” card when you return Ulti-Apelio, Ulti-Cannahawk or Ulti-Pettlephin to your Extra Deck.
Once per turn, by banishing 1 “Ritual Beast” card from your hand, Spiritual Beast Pettlephin allows you to target 1 card your opponent controls and return it to their hand. You can Tribute 2 monsters your opponent controls to Special Summon Lava Golem and then return it to your hand using Pettlephin’s effect. Just remember that you cannot Normal Summon during the turn you Special Summon Lava Golem.
If Ritual Beast Ulti-Apelio attacks, it is unaffected by other cards’ effects until the end of the Damage Step. Ulti-Apelio is basically able to ignore Sphere Kuriboh, Enemy Controller and Drowning Mirror Force, but this also means that Beatdown! and The Tie that Binds are your only way of increasing its ATK.
Once per turn, Ritual Beast Ulti-Cannahawk allows you to target 2 of your banished "Ritual Beast" cards, return them to the Graveyard and then add 1 "Ritual Beast" card from your Deck to your hand. You are going to activate this effect and then, before it resolves, you are going to return Ulti-Cannahawk to your Extra Deck and Special Summon 2 of your banished monsters (1 “Ritual Beast” and 1 “Spiritual Beast”). As long as at least 1 of your banished “Ritual Beast” cards are returned to the Graveyard, you will still get to add 1 “Ritual Beast” card to your hand.
Now you can banish another “Ritual Beast” card via Cannahawk’s effect and Special Summon Ulti-Apelio, Ulti-Cannahawk or Ulti-Pettlephin. Keep in mind that you can only Special Summon each “Ritual Beast” non-Fusion Monster once per turn, so you will not be able to return the “Ritual Beast” Fusion Monster to the Extra Deck and Special Summon Cannahawk and the monster you initially banished via its effect.
Ritual Beast Ulti-Pettlephin is a 2800 DEF monster that cannot be destroyed by card effects. Ulti-Pettlephin is essentially just an option that you might want to keep available for very specific matchups like Yubel.
If you don’t have Pettlephin or World Legacy Clash available, dealing with high ATK monsters can be very difficult. The Tie that Binds will reward you for swarming the field by giving you a reliable ATK boost that will also affect Ulti-Apelio.
Draw Sense: High Level is used primarily to search for Lava Golem. Both Herald of the Abyss and Cosmic Cyclone can enable this Skill.
As I mentioned, dealing with high ATK monsters can be a problem. Even if you were to run Quick as the WIND as your Skill, Ulti-Apelio would just disable the 500 ATK boost from Rising Air Current whenever it attacks.
You need at least 2 monsters on the field in order to Summon a “Ritual Beast” Fusion Monster, which makes it quite easy to disrupt your plays. You can still chain Ritual Beast’s Bond to a Treacherous Trap Hole or a Six Style - Dual Wield, assuming its activation doesn’t just get negated by Shi En, but you are obviously not always going to have it at your disposal.
