The thing to remember here is many main deck Karakuri monsters change their battle position when selected for an attack, so they can suddenly be forced into a situation where they have less attack
The effect is quite excellent, like ancient gear + honesty + negate effect, but there is a super fire monster called Hope Ray V in the same Hope derivation, and the effect overlaps with Numeron Force
If an attacking creature loses haste, perhaps because Fervor leaves the battlefield after attackers have been declared, it won't be removed from combat
Like other cards from the set, this Planeswalker comes with the transformation mechanic that lets him alternate between light and dark versions
That's right, even though it's a white card, the single flashback cost makes this enchantment remover a great option for decks running Quiet Speculation and/or Wild Mongrels
