I don't need to tell you why this is a good set, just look at the exclusives and imports alone and see. Not much else is known for any of the other exclusive cards, but we'll update as soon as we can.

Trifortressops

During either player’s turn, if your opponent Summoned 3 or more monsters this turn: You can Special Summon this card from your hand. If this card is Special Summoned this way, it is unaffected by other card effects, but loses 500 DEF during each player’s Standby Phase.

Mecha Phantom Beast Turtletracer

This card's Level is increased by the total Levels of all "Mecha Phantom Beast Tokens" you control. While you control a Token, this card cannot be destroyed by battle or card effects. Each turn, the first "Mecha Phantom Beast Token" you control that would be destroyed by battle is not destroyed.

Totem Bird

2 Level 3 WIND monsters
During either player's turn, when a Spell/Trap Card is activated: You can detach 2 Xyz Materials from this card; negate the activation, and if you do, destroy it. This card loses 300 ATK while it has no Xyz Materials.

Noble Knight Gwalchavad

This card is treated as a Normal Monster while face-up on the field. While equipped with a "Noble Arms" Equip Spell Card, this card becomes an Effect Monster with this effect.
● You can target 1 "Noble Knight" monster in your Graveyard; add it to your hand, and if you do, destroy 1 "Noble Arms" Equip Spell Card you control. You can only use this effect of "Noble Knight Gwalchavad" once per turn.

Noble Arms of Destiny

You can only control 1 face-up "Noble Arms of Destiny". Equip only to a Warrior-Type monster. Once per turn, the equipped monster cannot be destroyed by battle or by card effects. If this face-up card on the field is destroyed and sent to the Graveyard: You can target 1 Warrior-Type "Noble Knight" monster you control; equip this card to that target. You can only use this effect of "Noble Arms of Destiny" once per turn.

Mermail Abyssbalaen

This dude is near awful unless there's some super secret combo with him. But Whales with hammers are fucking awesome so who cares, I want a shirt with this dude on it.

Spellbook of Miracles

Target 2 Spellbook in your banished zone, attach them to an Xyz Spellcaster like Big Eye in your grave and special summon him. It's pretty meh.
