Shadowverse

Cost 8, body 3/3. Upon entering the game, deals 1 damage to a random enemy (important: enemy, not follower) as many times as there are cards in your hand. Most likely a legendary.



Cost 7, body 1/6. Ward. When a friendly follower dies, gains +1 attack. Maybe a gold card.



Cost 4, enhance - 9. 3-3. Without enhance, transforms an enemy follower/amulet into a Golem if a Sigil is present. With enhance, transforms all enemy followers and amulets into Golems. Legendary (I just want a Golem-themed card).



Cost 3, enhance 8, body 3-1. Without enhance, it's just a Knight (maybe with Storm), with enhance it transforms into a Dragon, has stats 7-4, and upon entering, deals 7 damage to all followers. Alternatively, it could be turned into a Dragon after evolving, but then the enhance is not needed; let them hold onto the evolves until round 8. Or Olive. With evolve - gold. With enhance - legendary, but then the non-enhanced version needs to have Storm.



Cost 6, stats 2-2. Summons skeletons until the arena is full. With this much Necromancy (usually 6), evolves all skeletons. Gold. Or legendary.



Cost 5, body 5/3. Rush. When played with other followers, deals 1 damage to both leaders. Gold.



Cost 8-10, body 4-4. When entering the game, fully restores the health of all allies. Legendary.
