the Great Ones is a series of Reptile-Type monsters based on the enemies (mostly bosses) in the famous video game, "Bloodborne". I previously wanna make them a Zombie-Type, but I realize that Zombies was already powerful so I decided to make them Reptiles, cause Reptiles was just a little weak so they needs more supports. Any suggestions?
Once per turn: You can Tribute 1 Reptile-Type monster you control; Special Summon 1 Reptile-Type monster from your Deck.
You can banish this card from the Graveyard; Special Summon 1 Reptile-Type monster from your hand, and if you do, it is unaffected by your opponent's Spell/Trap effects this turn. You can only use this effect of "Celestial Emissary" once per turn.
This card gains 100 ATK for each Reptile-Type monsters you control. Other face-up Reptile-Type monsters on the field cannot be destroyed by card effects.
Your opponent cannot target face-up Reptile-Type monsters you control for attacks, except this one. If this card in your possession is sent to your Graveyard by your opponent's card (either by battle or by card effect): You can Special Summon 1 Reptile-Type monster from your Deck, except "Rom, the Vacuous Spider".
If exactly 1 other Reptile-Type monster you control (and no other cards) is destroyed by battle or by card effect and sent to the Graveyard: You can target 1 card your opponent controls; destroy that target. This card must be face-up on the field to activate and to resolve this effect.
During either player's turn, when a card or effect that targets a card(s) on the field is activated: You can Tribute 1 face-up Reptile-Type monster you control; negate the activations, and if you do, destroy it.
