Second Goblin
Dark, Level 1, [Fiend/Union]
ATK: 100, DEF: 100
MFC-013, Common

"Once per turn, during your Main Phase, if you control this monster on the field, you can equip it to your 'Giant Orc' as an Equip Spell Card, OR change it back to a monster in face-up Attack Position. When equipped to a monster by this card's effect, you can change that monster's battle position once per turn during your Main Phase. (1 monster can only be equipped with 1 Union Monster at a time. If the monster that this card is equipped to is destroyed in battle, this card is destroyed instead.)"

Second Goblin is an interesting answer to the limitation of Giant Orc, and his effect makes him one of the more interesting Union Monsters. Many of these monsters seem like gimmicks, since both of the pair are often useless without the other. This is a definite exception, and it is to date the only Union Monster I have tried running.

With two or three Giant Orcs in your deck, it is definitely worth running at least one of this card to lessen the impact that Giant Orc has on field presence. A 2200 ATK Level 4 monster that remains in Attack Position after each attack cannot have its power understated. Also, even if your Giant Orc is overpowered in battle while it is equipped with this card, it gains at least one extra turn of precious life, where it could possibly be tributed for a Dark Ruler Ha Des or, even better, a Great Maju Garzett, who would arrive on the field with a dominant 4400 ATK.

For decks with Giant Orc, this card gets a Good rating. It's a bit of a shame that it is completely useless on its own and thus very inconsistent, but it is searchable even in Advanced format, it can be summoned by Mystic Tomato, and in a Fiend deck it can serve as food to Dark Necrofear once it is destroyed.
