Wyverns

[MagnetBomb]

So, here are my "Wyvern" Archetype cards so far, hoping to make more. I know there are OCG errors, and I was hoping that someone could help me with them.

[spoiler=Monsters]

When this monster is destroyed, you may choose one of these effects:
-Summon one level four or lower "Wyvern" monster from the graveyard
-You gain 1000 life points


Its strong scales protect it from most of the attacks of the other forest animals.


Once per a turn, you may select one "Wyvern" monster on the field other than this card. This monster cannot be targeted by effects or attacked for one turn.



For every monster sent to the Graveyard by this monster, it this monster gains 200 ATK Points. If this monster is sent to the Graveyard, increase the attack of one "Wyvern" monster by 400 ATK points


When this card is destroyed by battle, your opponent looses 1000 life points.

[spoiler=Spells]


Every time a "Wyvern" monster is destroyed, you may activate one "Wyvern" monster's effect, regardless of circumstances.


Choose one "Wyvern " monster on the field or in your hand. Send it to the graveyard. Select one "Wyvern" monster on the field. The selected monster gains half the ATK points of the sacrificed monster
