New ability and spell ideas

Question

We have been playtesting the game for a little bit now, and with the deck builder it is finally possible to see what an optimal deck might be, and what the flow of games will really be like.

Because of this, I have come up with a list of spell ideas that I think would be a good fit for the current game.  For most of them, the costs would need to be determined by playtesting, as well as any values for X. Here is the list:

Gain 3-5 scrap this turn only (costs 3 or less mana, probably 2)

Destroy all bots, players gain their scrap value

Destroy one Bio unit immediately

Remove all buffs/enchantments from one Bio

Opponent cannot scrap cards next turn

Opponent loses all scrap

Steal X scrap from opponent

Opponent cannot play Bio units next turn

Deal X damage to all Bots 

Your Bots gain X attack this turn only.

Your Bots gain X health next turn

Buff a Bio unit X/X for a cost in mana (no scrap cost)

Buff a Bot by X/X costing all of your scrap

The next enchant you play this turn costs 0 scrap

Opponent cannot play enchantments next turn

I have also thought of some thematic reasons why some of these may be applicable but for now I will not post them here.  I understand that some of these ideas might be overpowered, but it will be very difficult to tell which and by how much without further playtesting.  Please post any other ideas that you have in this question, and also any criticism of any of these ideas.

Just as a side note: I am intending on *supporting* all of these. And more.

Another idea I just had: "You gain twice as much scrap when Scrapping a card"

Answer 1

Gain 3-5 scrap this turn only (costs 3 or less mana, probably 2)
This turn only? I like that!

Destroy all bots, players gain their scrap value
This reminds me about Day of Judgement in MTG, and there's some related HS cards as well for it. I like that they are automatically scrapped. This is a powerful card if you have more cards than your opponent on hand and should probably have quite high casting cost.

Destroy one Bio unit immediately
Powerful. Perhaps a bit too powerful. At least given how the current attack system works.

Remove all buffs/enchantments from one Bio
Removing *all* might be a bit excessive. But removing one or two enchantments might be reasonable. Although again, how the current attack system works this might be very powerful.

Opponent cannot scrap cards next turn
This one I *really* like. This can lead to some different strategies. I like the thought of preventing opponent from doing something.

Opponent loses all scrap
Aaaw. Poor opponent. I think he'll survive. Sounds like a reasonable effect. Then you'd be more careful with scrapping, probably. I just hope this isn't too powerful.

Steal X scrap from opponent
Stealing scrap? Sure, why not? X should probably be quite low though.

Opponent cannot play Bio units next turn
Again, I like the thought of preventing opponent from doing something.

Deal X damage to all Bots
I think this better than destroying all creatures. Especially if this damage can be combined with actual attacking to destroy "creatures".

Your Bots gain X attack this turn only.
X should probably be quite low.

Your Bots gain X health next turn
Seems useful for a defensive strategy

Buff a Bio unit X/X for a cost in mana (no scrap cost)
Hmm. I am not sure about this. Perhaps if it is "this turn only"

Buff a Bot by X/X costing all of your scrap
What if I only have one scrap? Should the X be dependent on my scrap or something? If it is, then I think it can work. Should perhaps be "this turn only".

The next enchant you play this turn costs 0 scrap
I like the card, but I would probably not play it myself. But I think that it is a good card to add to get some players to think "Hmm, this I could combine together with that to make a super über combo".

Opponent cannot play enchantments next turn
Oh how I would love to have had this card when I played you recently!

 

I'd also like to see...

Cards with various bonuses / drawbacks such as: (some more or less crazy examples)

1/4 B0T for 3 mana: At the beginning of your turn, draw an extra card
4/4 Bio for 3 mana: You may only play one card per turn.
2/2 Enchantment for 2 scrap: Enchanted creature can only attack each 2nd turn.
3/3 Bio for 3 mana: Your enchantments costs twice as much scrap.
5/5 B0T for 3 mana: All your creatures have maximum 5 attack
0/7 Bio for 6 mana: Your opponent can only attack with one creature each turn

These bonuses and drawbacks can of course be made in several different variations to find out what works best.

Note that you don't need to worry about how these cards should be implemented. I assure you, they will be able to be implemented.
