Card Rules: Rulings powered by The Netrep API. Note that 'Heavy Mech Support Platform' is different from other Union Monsters in that its last sentence is applied if the monster it is equipped to is destroyed (period) , not just when the monster is destroyed as a result of battle. This extra effect does not apply to previous Union Monsters. If a monster equipped with 'Heavy Mech Support Platform' is targeted by 'Ring of Destruction' then 'Heavy Mech Support Platform' is destroyed instead of the equipped monster and the damage inflicted to both players by 'Ring of Destruction' is 0 (because the monster targeted by 'Ring of Destruction' was not destroyed by it). If you have a monster 'X-Head Cannon' for example equipped with 'Heavy Mech Support Platform' and you activate 'Limiter Removal' the ATK will becomes (1800 + 500) x 2 = 4600. Also the 'Heavy Mech Support Platform' will be destroyed instead of the 'X-Head Cannon' during the End Phase (by the effect of 'Limiter Removal') and 'X-Head Cannon's' ATK will no longer be doubled. If 'Heavy Mech Support Platform' is equipped to 'Big Core' or 'Reflect Bounder' and they would be destroyed by their effect 'Heavy Mech Support Platform' is destroyed instead. If 'Reflect Bounder' equipped with 'Heavy Mech Support Platform' is attacked by 'Dark Ruler Ha Des' during damage calculation 'Heavy Mech Support Platform' is destroyed instead of 'Reflect Bounder'. Then after damage calculation 'Reflect Bounder' will destroy itself by its own effect. Its effect is not negated because it was not destroyed by 'Dark Ruler Ha Des'. [Re: Cyber Phoenix] While you have 'Cyber Phoenix' on the field in Attack Position 'Heavy Mech Support Platform' can be equipped to a Machine-Type monster on your side of the field but all of its effects are negated. It will not increase ATK or be destroyed in place of the equipped monster and it cannot be unequipped & Special Summoned by its own effect. (The Machine-Type monster can still only be equipped with 1 Union Monster at a time because that is a condition not an effect). [Re: D.D. Trap Hole] If you select your monster equipped with 'Heavy Mech Support Platform' for your monster to destroy with 'D.D. Trap Hole' then 'Heavy Mech Support Platform' is destroyed instead and is sent to the Graveyard. Your opponent's monster is destroyed and removed from play. [Re: Gyroid] If 'Gyroid' is equipped with 'Heavy Mech Support Platform' the effect of 'Gyroid' will prevent both from being destroyed in battle. If attacked again the same turn and 'Gyroid' would be destroyed 'Heavy Mech Support Platform' will be destroyed instead. A third attack will then destroy 'Gyroid' normally. [Re: System Down] If 'Heavy Mech Support Platform' is equipped to a Machine when 'System Down' is activated the equipped monster is removed from play but 'Heavy Mech Support Platform' is just destroyed and sent to the Graveyard.
