If this card is Normal or Special Summoned: You can Special Summon 1 "Pumpkin Carriage" from your hand or Deck, then, if "Golden Castle of Stromberg" is in a Field Zone, you can equip 1 "Glass Slippers" from your Deck to this card. But still, Stromberg is just so intimidating. Has the negative effect of Hans being on the field but the searching capabilities are decent. You can only use this effect of "Iron Knight" once per turn. If this card on the field is destroyed by battle or sent to the GY by a card effect: You can add 1 "Iron Hans" from your Deck to your hand, or, if "Golden Castle of Stromberg" is in a Field Zone, you can add 1 Warrior monster from your Deck to your hand, instead. Loses 1000 ATK while you control "Iron Hans". Imagine easily getting out Stardust Dragon or maybe one Extra Deck monster that prevents the Banish effect of Stromberg. Oof? But that effect for Special Summoning Extra Deck monsters is great.
Though Wall of Disruption and other Backrow can easily stop it. Running 2 Iron Knights basically makes this a 3200 Beatstick. Gains 1000 ATK for each "Iron Knight" you control, while "Golden Castle of Stromberg" is in a Field Zone. You can only use this effect of "Iron Hans" once per turn. If this card is Summoned: You can Special Summon 1 "Iron Knight" from your Deck, also if "Golden Castle of Stromberg" is not in a Field Zone when this effect resolves, you cannot Special Summon monsters from the Extra Deck for the rest of this turn. Though its stats lead much to be desired. This I can see being decent, since it's Backrow removal and it can search the Field Spell. You can only use this effect of "Glife the Phantom Bird" once per turn. If this card is Normal or Special Summoned: You can target 1 card in your opponent's Spell & Trap Zone destroy it. You can discard this card add 1 "Golden Castle of Stromberg" from your Deck to your hand. But if there's a card that'll return banished cards to the deck, then maybe it could work? Well, this is a R anyway in the new Mini BOX. And 50% of your deck if you're running 30 Cards. So you'll be losing about 75% of your deck if you're running 20 Cards. Since we can only have at minimum 20 cards and at maximum 30 cards.
When your opponent's monster declares an attack: Destroy the attacking monster, and if you do, inflict damage to your opponent equal to half the ATK that monster had on the field. You can only use this effect of "Golden Castle of Stromberg" once per turn. You cannot Normal Summon/Set the turn you activate this effect (even if this card leaves the field). During your Main Phase: You can Special Summon 1 monster from your Deck that specifically lists the card "Golden Castle of Stromberg" in its text. Once per turn, during your Standby Phase, you must banish 10 cards from the top of your Deck face-down (this is not optional), or this card is destroyed.
