Card-specific notes from database

• (YGOResources) Only one Trigger Effect that Special Summons the activating monster itself from the hand (or hand/GY) can be activated in any given Chain. If multiple such effects meet their activation conditions at the same time, you can only activate one of them.
• (YGOResources) If this card and another monster are Special Summoned simultaneously by a card effect while a restriction like "Rivalry of Warlords" or "Gozen Match" is applying, you must send monsters to the GY to comply with the restriction immediately after the effect finishes resolving (unless the restricting card was destroyed during that same resolution).
