Machine, Fairy, or Fiend: Once per turn, if you activate a monster effect (except during the Damage Step): You can target 1 face-up monster you control; it gains 1000 ATK (even if this card leaves the field). If 2 or more cards are in the same column, you can Special Summon this card (from your hand) in that column. You can only Special Summon "Mekk-Knight Yellow Star" once per turn this way. You can banish 1 "Mekk-Knight" monster from your GY, then target 1 Spell/Trap in this card's column; destroy it. Overall I do think this is a solid set. There were some questionable choices, however. I do think making Wind-Up Kitten and 2 Rikka cards take up Ultra slots in this set was a weird choice. Also out of all the Photon cards to reprint and make a Collector’s Rare, I would of rather something like Number 90: Galaxy-Eyes Photon Lord or maybe even Number 38: Hope Harbringer Dragon Titanic Galaxy over Photon Orbital, but that’s fine. I also would of chose Spellbook of Judgment to be in here as a Collector’s Rare over Spellbok of Fate. The only card I feel should of been a Collector’s Rare that wasn’t was probably Ancient Fairy Dragon. With all that out of the way, all the new Gate Guardian support is super cool and the imported cards from the History Archive Collection are nice to finally have for competitive and casual players, alongside collectors. There are solid reprints in here like Baronne de Fleur, Guardian Chimera, Solemn Judgment, Mekk-Knight Crusadia Avramax, etc. Even the Wind-Up Kitten and Rikka stuff is good to reprint, even if the rarity choices feel like a miss. Also a few nice things that needed reprints like Kalut the Moon Shadow and Nimble Anger to name a few. Overall a solid set that will likely age well to similar success of sets like Toon Chaos and to a lesser extent currently King’s Court.

Now before we look at the regular reprints in this set, I’ll take a second to spotlight Ancient Fairy Dragon since there is a key feature to note here. As we noticed on the February F/L List, Ancient Fairy Dragon’s return to Limited status took effect on March 10th (the offical release date of this set). This is due to the fact that the card has received an errata in this set to change its effects to be more acceptable in the current game enviorment. Now, the abilitiy to summon a Level 4 or lower monster from your hand by giving up your Battle Phase remains the same, only now it is a hard once per turn instead of a soft once per turn, meaning you can’t use this effect with multiple copies in the same turn. The hard once per turn also applies to destroying a Field Spell to gain 1000 LP and search another, just now you must add a Field Spell with a different name from any destroyed Field Spell, making sure you have to use multiple different Field Spells to get the most value from this effect. You'll have another chance to smash the competition with one of the most powerful Synchro Monsters around - Baronne De Fleur! Warrior, Beast, or Pyro: Once per turn, if you activate a Trap Card (except during the Damage Step): You can target 1 card your opponent controls; destroy it.

Number" monsters you control with a number between "101" and "107" in their name, as well as "CXyz" monsters and "Number C" monsters you control, cannot be destroyed by your opponent's card effects, and your opponent cannot target them with card effects. Once per turn, if you Special Summon an Xyz Monster with a "Rank-Up-Magic" Spell's effect: You can target that Xyz Monster and 1 monster your opponent controls; attach that opponent's monster to that Xyz Monster as material. If you control a Spellcaster monster: You can banish up to 3 "Spellbook" Spells from your GY; apply this effect, depending on the number of Spells banished for this card's activation. You can only activate 1 "Spellbook of Fate" per turn. Paying homage to fan-favourite reprints, the collection features an array of beloved cards masterfully reimagined for today's challenges.
