[I Hate Snatch Steal]

 

If your opponent controls more monsters then you do, you can normal summon/set this card without tributing. If this card is summoned: you can add 1 spell card from your deck to your hand that that destroys a card(s) when its activation resolves If you do not have a "Silvermage" monster with a different name on your side of the field or in your graveyard, you must have a "SIlvermage" monster in your hand to resolve this effect. You can only use this effect of "Silvermage of Destruction" once per turn.

If this card is normal summoned: you can excavate the top card of your Deck, and if it is a Spell Card, add it to your hand, otherwise place it on the bottom of your Deck. If this card is sent to the graveyard: you can add 1 "Silvermage" monster from your deck to your hand, except "Silvermage's Apprentice".

If you control a "Silvermage" monster: Target 2 level 4 or 2 level 6 monsters in your Graveyard; Xyz Summon 1 Xyz Monster using those 2 monsters as the xyz materials.
