Fixed wordings
(will update the actual cards a bit later since I have to reupload them, and if any more changes are needed then uploading them now would be a bit of a waste.)
I have a template up for a reason. Lemme help you with what I think you should do.
Tail Spear of the Tyrant Dragon
Equip Spell Card
Equip only to a "Tyrant Dragon" monster. The equipped monster Gains 1000 ATK. If the equipped monster battles a defense position monster: inflict piercing damage to your opponent. If you control no monsters, you can reveal this card in your hand and send two cards from your hand to the graveyard: Special Summon 1 "Tyrant Dragon" from your graveyard.
Supreme Tyrant Dragon
Level 12 FIRE Dragon-type Fusion monster
3900 / 3000
"Tyrant Dragon" + "Tyrant Dragon" + "Tyrant Dragon"
If this card was fusion summoned using the effect of "Dragon's Mirror", shuffle the fusion materials used for this card back into the deck.
This fusion summoned monster is unaffected by your opponents trap and monster effects. This card can attack all monsters your opponent controls once each.
Tyrant Dragon Overlord
Level 8 FIRE Dragon-type Effect monster
2900 / 2500
When you tribute summon this card, you can banish dragon-type monsters from your graveyard as monsters required for the tribute summon. Your opponent cannot activate cards or effects in response to this card's summon. This card cannot be targeted by spell cards your opponent controls.
@SillyPhillyI'm fine with you helping other players. However, if it is a balancing issue, that's my own domain and I would prefer if you stayed out of it. I've already threatened to ban two players. I don't like being the ban-happy GM. This is your second warning, however. If you do it again, I will ban you.
