Metaion, the Timelord

Metaion, the Timelord

Cannot be Special Summoned from the Deck. If you control no monsters, you can Normal Summon this card without Tributing. This card cannot be destroyed by battle or by card effects. You take no Battle Damage from battles involving this face-up Attack Position card. At the end of the Battle Phase, if this card attacked or was attacked: Return all other monsters on the field to the hand, and inflict 300 damage to your opponent for each card returned. During your Standby Phase: Shuffle this card into the Deck (even if face-down).

about the token "ojama trio" for example. It would surely not return to the hand. BUT, does the effect of destroying the token counts?

3 token (if destroyed = 900 damage) then does the effect of Metaion also be counted or not?

To put is simple, Metaion attack 3 ojama tokem what is the end result and Total damage?

This card cannot be destroyed by battle or by card effects.

also I like to ask further explanation on this. does it mean that "Trishula, Dragon of the Ice Barrier" (or other similar monster) effect can be negated?

For trishula that part, metaion is still can be banish by monster that remove from play monster without destroy the monster such as BLS, Chaos sorcerer, Trishula.

For special case, metaion can be send to grave without destroy it by effect of dark end dragon.

For token that part, well i not good at token monster rulings, so i don't know.

RFG=/=Destroy, ever.
As for the tokens, they just disappear, they're not destroyed.
