Pack of Frozen Stars - Critique my Den! [Cool Base Breeding Project]

Hello! Let's keep this short and sweet: I'm a newbie, and I've got a goal: I want to breed at LEAST one of every Cool base in the game currently! Here's where you come in:

Judge my Den!

I'd like some input on which wolves I should keep or toss in my quest for the best! I'll link my den here for easy access:

Pack of Frozen Stars

Don't want to comb through my den? That's fine! Here's every wolf I've gotten so far:

Adults!

Adder

Bullion

Ryegrass

Sleet

Pups!

Sunbeam

Will-o-the-Wisp

In addition to any critiques and advice, I'd also love to find any recommendations of good Studs or good threads to buy some reasonably priced wolves! Keep in mind I'm not able to afford much as a new player (I quite literally registered the minute the site opened) so any suggestions would be great!

I'm not sure if your interested, but here's my alpha Toska . Also Bullion is super pretty !

:O Toska's gorgeous! I love the beige markings, but unfortunately I'm not sure his base would toss any of my current females a Cool base (Cool as in the base group, not the adjective!! He'd definitely make some dope pups!) Thank you for the comment on Bullion! I made him in homage to the Ornament base on Lioden ^^

Do you have any recommendations on which wolves should be kept or used for breeding for the goal I'm after?

He is a gorgeous lead male! Looks absolutely striking, but since I'm going for a Cool only den I'd like to avoid the chances of being thrown pups from other base groups :,) I AM going to be putting Snowshoe up for trade fairly soon, she's taking up valuable slot space and is fairly proficient in scouting along with having good stats for an NBW. While I'd prefer SC I'd be willing to look at item offers as well! I'll message you the link to her trade in a few days once it's up :>
