Practically any clan mixes well with Skeelz but especially the clans with strong combat bonuses (Uppers, Montana, Bangers, Ulu Watu, Vortex) in a 5+3 preset. Your Skeelz characters ignore SOB and also function at almost full capacity when their bonus isn't active.
Mono skeelz is competitive but you won't get too many easy wins. Mono Skeelz has arguably the most consistent draws of any preset as their low * characters are fantastic. A 10* Skeelz hand can compete with a typical 14* or 15* hand.
I find it is very hard not to make a mono out of skeelz
Must so far they are even used with other mono decks so good combo.
next we have snowflake michael greem all fantastic cards let say you pick
Chiara Redra Michael Greem 14*
2 high power 1 devastating dmg 1 dr , pretty good before we can look for other halfdeck we see sandro and sasha 7/2 + 16 an 10/4 both reliable pretty hard to pass up
Chiara Redra Michael Greem Sandro Sasha 19*
Next two is personal preference or would require insane amount of testing to determine which is the most effective,but 1 dr card is highly recommended
Snowflake / Deebler , Uranus , Danae , Praxie
Jay , Corvus , Belgosi / Liam , Spiaghi
I prefer Snowflake / Deebler
