Lone Player

[Thomas★Zero 19]

Lone Player
Continuous Spell Card
While you control only 1 monster that was summoned from the Extra Deck and you control a monster thats in your Extra Monster Zone, that monster in your Extra Monster Zone cannot be destroyed by battle or by card effects and all damage you take involving that card becomes 0.

So Lone Player is a Continuous Spell that focus's on a single key Extra Deck monster where it grants it massive protection where in decks that focus on that card Extra Deck Monster evolving (like Utopia or Red Dragon Archfiend) this card can be handy for adding that layer of protection to it.

What do you mean by your Extra Monster Zone? As far as I know, there isn't necessarily an Extra Monster Zone that belongs to a specific player. Anyways, Sky Striker is pretty much yelling in my ear when I read this card, which kind of brings up mixed feelings. On one hand... it's Sky Strikers. On the other hand, it is unsearchable and cannot be recovered by Sky Striker Spell/Traps. Considering however the recent nerf Sky Strikers apparently got, then the card could be alright. In any other case, this card is good.
