I'm writing out Spirit Tracks bosses as cards because I can't be bothered to make cards in Pop Culture section

[Lonk]

Stagnox, Armored Colossus

EARTH

Insect/Effect

Cannot be Normal Summoned or Set.  Must first be Special Summoned (from your hand) while you control a "Forest".  This card cannot be destroyed by card effects, and any monster that battles with this card has its original ATK and DEF halved during the damage calculation.  When this card battles a WIND monster, this card's ATK and DEF become 0 until the End Phase.  You can only control 1 face-up "Stagnox, Armored Colossus".

 

Fraaz, Master of Icy Fire

Level 8

WATER

Pyro/Effect

ATK 3000/DEF 2000

 

Cannot be Normal Summoned or Set.  Must first be Special Summoned (from your hand) by banishing 1 FIRE and 1 WATER monster in your Graveyard.  This card cannot be destroyed by battle when battling a non-WATER or non-FIRE monster.  When this card is destroyed and sent to the Graveyard:  Special Summon 1 "Ice Fraaz Token" (Level 4/WATER/Zombie-type/ATK 1500/DEF 100) and 1 "Fire Fraaz Token" (Level 4/FIRE/Zombie-type/ATK 1500/DEF 1000).  When either a "Fire Fraaz Token" or "Ice Fraaz Token" is destroyed, and there are no "Fire Fraaz Tokens" and "Ice Fraaz Tokens" on the field:  You can Special Summon this card from your Graveyard.  When this card is Special Summoned this way:  Discard all Spell and Trap Cards in your opponent's hand.  You can only control 1 face-up "Fraaz, Master of Icy Fire".

Besides Phytops, I believe the effects of the cards matches the flavor of the bosses?

[Serefin]

I actually have Spirit Tracks, and I can attest that Stagnox and Fraaz have effects that I would expect them to have in the card game.

 

Phytops seems off, however. I would suggest doing something more with the Poison Barb counters. How about making so that, once per turn, before the Battle Phase, you can remove all Poison Barb counters on one monster to have Phytops gain ATK equal to the amount removed *100, and this boost lasts until the End Phase. I don't remember his battle that much because it was boring, but I do remember him being able to "regrow" his spikes.

 

As for Cragma and Skeldritch, I can't comment on them. I've fought Cragma before, but I forgot what the battle was like, and I don't even know what Skeldritch looks likes because I could never play the Lokomo Song with the Sand Lokomo. So, I will discuss their effects  in regards to the actual game.

 

For Cragma, his ability to cause effect damage is a little OP. At any point in a duel your opponent can have anywhere from 0-5 monsters on the field of varying ATK and DEF levels. If your opponent has, just as an example, The Wicked Dreadroot on the field right next to, I don't know, Elemental Hero Thunder Giant, you could ram Cragma into TG and deal 2000 points of damage to your opponent; 1000 for the battle and another 1000 for the destruction of Dreadroot. I think you should change it so the effect only deals 300-500 damage per card destroyed.

 

For Skeldritch, I don't really have many complaints beyond the fact that your opponent could ram a few monsters into it then finish it off with card effects, and if it succumbs to a card effect, it has to be banished to give you a (rather lackluster) piece of compensation.

That's a good continuation with Phytops there.  Also, I will nerf Cragma a bit.
