Two Rare creatures,

[Sorandu]

Static Wisp

1RR

Creature — Elemental Spirit

Static Wisp gets +3/+0 as long as you control no untapped creatures.

Tap an untapped creature you control: Static Wisp gains first strike, trample, or haste until end of turn.

3/1

Vineweaver Druid

3G

Creature — Elf Druid

Hexproof

Whenever a creature enters the battlefield under your control, you may put a +1/+1 on it. If you do, put a +1/+1 counter on Vineweaver Druid.

3/3

Thanks for any feedback.

That druid will quickly get very, very, very nasty. Imagine it with Ant Queen or another mass token maker.

Static Wisp being able to always have its buff makes it significantly stronger and requires a higher cost. It would be more interesting if you had to tap multiple creatures meaning it's an actual decision to activate or attack.

I would like to honestly ask why the counter is a you may? The scenarios where you don't want to are so rare that it seems asinine to bother with the you may. Thw ability could then be rewritten to just put the counter on both of them shortening it.

Yes, Vineweaver Druid's antecedent Juniper Order Ranger just puts the +1/+1 counter on both; this is one of those things that I feel it's right to simplify for digital platforms unless the card has some sort of drawback in and of itself that would result from the +1/+1 counters, in which case it would depend on the exact design.

Speaking of which, I think the Druid's hexproof puts it beyond the pale in power terms. The Wisp is a really cool idea but I do agree that its activated ability should cost "Tap two untapped creatures you control..." instead.

[Sorandu]

I totally forgot about Juniper Order Ranger. Having limitations on the triggered ability would make it more interesting and balanced. How about this:

Vineweaver Druid

3G

Creature — Elf Druid

Whenever a nontoken creature with power 2 or less enters the battlefield under your control, put a +1/+1 counter on that creature and a +1/+1 counter on Vineweaver Druid.

3/2

I don't think you need the power restriction as long as you have the nontoken one. It gets a lot harder to drop many creatures in a turn to grow the druid when tokens aren't counted. So something like "Whenever a nontoken creature enters the battlefield under your control, put a +1/+1 counter on that creature and a +1/+1 counter on Vineweaver Druid".

[NUMBERS]

I think I agree with [mention]Krishnath[/mention] on not needing the power restriction if you have the non-token restriction. But conversely, I could see having the power restriction but not the non-token restriction. Either way is probably fine as long as you drop Hexproof I would think.

I really, really like what you did with Static Wisp, but it does seem a little too easy to turn on // too much payoff for that difficulty. Not sure how I would address that, simplest way is probably dropping its buff power by 1? But I'm not exactly happy with that suggestion, as it doesn't feel right to me.

I think that as a rare, Static Wisp is about right for the power level and stats. It's a fragile creature, and if you play it without having any other creatures on the battlefield, you simply have a 3/1 vanilla rare for the turn which isn't the most exciting play. It's a twist on Ball Lightning and the like in that instead of having the haste/trample effect automatically on it, you have the player work for such effect. The lack of an end-of-turn sacrifice effect feels different to other cards of the like. Cool design.
