1. Not sure if I can just say this artifact taps for .

2. I'm not sure what to cost this at. 5 is too high since it's a bad Gilded Lotus, but I was worried 3 might be too good since you could just have 3 snow lands.

The flavor of the restriction is that the Frozen Lotus can't bloom again unless it's cold enough.

It should go 1. then 2. but I don't understand the formatting. I have two there in the text, but I don't know why the second line indents and changes the 2 to 1.

What does "Add ." mean? is a cost representing mana produced from a snow source (IIRC the current rules say "snow permanent" since WotC decided only using it like that, but it's a common change for custom cards and entirely feasible - also the difference is irrelevant to this card), so if you want a permanent to produce mana that is able to pay for it needs to be a snow permanent that is able to produce the mana to pay for .

Now there are cards that can remove the snow type from a permanent, so this could conceivably be a nonsnow permanent that says "Add ." and that mana cannot be used to pay for a cost. That's weird.

There are already artifacts and creatures that show you how to word this. Why are you not looking those up? That's like day 0 research when including snow mana in your set: Look at what snow mana is and how it has been used... Sorry. Watching too much CinemaSins makes me rant.

Just... Boreal Druid.

How does that lead to:

> Frozen Lotus doesn't untap unless you control less than five snow permanents.

? Wouldn't "cold enough" be better represented with MORE snow permanents?

> It should go 1. then 2. but I don't understand the formatting. I have two there in the text, but I don't know why the second line indents and changes the 2 to 1.

Are you missing a space after the "1."?

I was missing a space after the 1. I had no idea that would affect the formatting here.
