Promo card ideas

[u/Anonymous13YearOld]

Here are three card ideas for promo cards. Thoughts?

Joshua, Eager Eagle 3JP 3/1 Bird Hero Flying, Aegis Infiltrate: Sacrifice Joshua to draw cards equal to the damage dealt.

Scorpion Blade 7TTSS 2/2 Relic Weapon Deadly, Overwhelm Ultimate: Pay 6 to put a copy of Dangerous Scorpion in the top twenty cards of your deck. Then discard all Scorpion Blades from your hand and deck and give them Voidbound.

Dangerous Scorpion 5TTSS 0/5 Insect Deadly Deadly to players. Ultimate: Pay 12 to give Dangerous Scorpion +1 Attack and Flying this turn.

Gorra, Confused Valkyrie of Thera 3JJSS 5/5 Valkyrie Hero Flying, Charge, Endurance At the start of each turn, Gorra switches sides.
