Metamorphosis has been banned for a very long time, which is quite understandable given that it’s quite a powerful effect for such a little cost
Spell - Normal
Tribute 1 monster. Special Summon 1 Fusion Monster from your Extra Deck with the same Level as the Tributed Monster.
It’s a good effect, but the only time we had to see it in action was 2005. It was banned for 12 years afterward, and a lot of new mechanics, monsters, and such have been introduced since it was created.
One notable thing about the level 10 section was that these cards are quite accessible, given that railway as an archetype allows for easy summons of level 10 monsters. Level 8’s are theoretically good in blue eyes, 5’s could be good in cyber dragons, level 6/7 could be good in pendulum magicians given that astrograph sorcerer and chronograph sorcerer exist for easy summons, I have no idea how you would get to level 9s or 12s on a regular basis though.
Would this card still be meta relevant? It’s unsearchable, since it’s not a fusion card it’s quite unsearchable by any good cards, unless you can actively rely on left arm offering to search it and still summon a good monster with the effect.
( all of the good cards that can be summoned by this effect are listed below. Levels not present have no good fusion monsters to summon. Normal monsters are not included. Banned monsters are not included either. )
( a monster that states ( a fusion summon of this card must be done with the listed materials ) or any variation of that can be summoned with metamorphosis since summoning it with this card is not a fusion summon )
