Spirits suck... your mana

So there is this one card I really like in Hearthstone called Mana Wraith. The reason I love it, is because it is such a unique way to win. It gives the game a twist, which might give you an edge on the battlefield. That is, if you own another cheap minion and your opponent doesn't. I would like to see more of this minion, but it sadly isn't that great.

So I came up with the idea to have a minion that gets stronger with each mana spend to cast it. Because who would want that, right? No one expect for me and my crazy ideas. But take a moment to think about it. This card would make so many other cards / abilitites more useful:

Elusive Banshee = 2/3 for 2 mana.
With Mana Wraith = 3/4 for 3 mana.
With Chieftain Scarvash = 4/5 for 4 mana.

With Naga Sea Witch = 5/6 for 5 mana.

With Venture Co. Mercenary = 5/6 for 5 mana

This card also makes Piloted Shredder a tiny bit weaker. Making it possible for the player to get the 0/1 Stealth minion blocking a slot on his side of the board. That is, unless the player can buff it of course. 

Anyway I like this idea. I hope you guys like it too. Let me know what you think of it!

Pathaleon the Calculator

After my somewhat disappointing Satyr tribe, I’ve stopped creating new Custom Cards. However, lately I started to tinker again. When I was browsing the Wowhead database I remembered this particular instance boss. He has two abilities that I liked and I wanted to incorporate them in the game. Pathaleon the Calculator uses his Mana Tap ability to drain his opponent's mana and uses it to summons Nether Wraiths.

Hearthstone could really use some more Blood Eleves and a 4 CMC Legendary would be nice. So I came up with the following design: "At the End of Each turn, summon a 1/1 Nether Wraith for each unspent mana that turn." This basically forces your opponent to empty his mana pool. On turn 5 this minion is a 4/5 for 5 mana. Which isn't that strong. However, on turn 10 he will hit the board for 8/9 power/toughness. That it, if you play no other cards of course.

Personally I don't think it's the best card out there. But it is something a bit new and that's what I’m searching for. New abilities that we haven't seen until now in Hearthstone.
I hope you like the card. Leave comments below! :P
