Alright, got to do a few of my puns!

LEVEL 6 - DIPLODOCUS POCUS

(COOKING UP SOMETHING): When  this card takes damage, put a number of counters on it equal to the amount of damage taken.

IT'S NOT READY YET!: This card gains Levels equal to half of the counters on it. Take out all counters.

BIG MAGIC: Deal damage up to twice the amount of counters on this, distributed among any cards. Take out all counters.

Basically a cannon that you need to charge up. A good technique would probably be to not attack it at all, but the player could technically attack it with their own cards and use it more carefully.

LEVEL 4 - ARCANEOPTERYX

(SOUL STAFF): When this card defeats another card, one card you control may gain 1 Level.

FELL SWOOP: Deal 1 damage to up to 3 cards of Level 1 or lower.

A cleaner/scavenger basically, really nice against swarms, and can help bulk up your big dinos (or themself!)

LEVEL 0 - MYRIADISCHIA

(COLORFUL ARRAY): Whenever you play a card of Level 1 or lower, you may attach it to this card. Attached cards cannot use any Abilities or be targeted. Whenever this card takes damage, instead discard an attached card.

(PACK HUNTING): This card may act a number of times equal to the amount of cards attached to it.

NIBBLE: Deal 1 damage. Can be prevented, not reduced.

A little weird idea of making mirischias into colored sprite-imps that swarm up but without exposing themselves to multiple target threats. Also it might be worded a little ambiguously in some parts, I hope it's understood or at least the mystery is fun.

GOOD STUFF! I love me some raptors and oh my god I just noticed is that just a chicken?
