I'll probably end up ninja'd, but here goes.
It wasn't that the card itself was bad. It's that it was improper card grammar.
Firstly, all archetypes should use proper capitalization in the card effect, or the card(s) the effect is looking for will fail to exist. Example: If an effect is looking for any form of "Elemental HERO" or "Destiny HERO", but the card text says "Hero", then instead of "Elemental HERO" and "Destiny HERO" monsters, we get "Heroic Challenger" monsters simply because of capitalization.
Secondly, saying a card gains "200 attack" is improperly saying that a monster can attack 200 times. This, of course, is irrational. That's why there is the term "ATK". Though you pronounce this term "Attack", it has a completely different meaning that the basic word "attack". This is similar to how in English, we have "they're" (they are), "their" (belonging to them), and "there" (a location). The same goes for "DEF" vs. "Defense".
Thirdly, there are terms that, no matter what, are capitalized when writing card effects. These are: "Summon" (and any distinction of Summoning form mentioned beforehand, such as "Normal", "Special", "Fusion", etc.), "Monster" ONLY when preceded by a specific monster type ("Effect Monster", "Ritual Monster", "Synchro Monster", etc.; NEVER use "Monster Card" unless speaking about a "Monster Card Zone"), "Spell/Trap Card" (and any kind of special "Spell/Trap Card"), "Zone", "Deck", "Graveyard", "Extra Deck", and any monster type ("Warrior-Type", "Beast-Type", etc.). Examples of terms that you shouldn't capitalize are "field", "hand", and "banish(ed)".
Fourthly, ALWAYS put archetypes or parts of card names in quotation marks when used in card text. If you have a card that is supposed to search for a "Dark Magician" from your Deck, but don't put "Dark Magician" in quotation marks, then it breaks the card effect.
Finally, when speaking of monster types, NEVER leave off the suffix "-Type". This is because a "Warrior" and a "Warrior-Type monster" are two completely different things. a "Warrior" is a monster with "Warrior" in its name. For example: "Junk Warrior", "Stardust Warrior", etc. A "Warrior-Type monster" could be "Dark Blade", "Buster Blader", "Gaia the Fierce Knight", etc.
Just try to stick to this. There's more, but those are some of the most important rules to stick to.
