Perhaps it is something like: you need both cards in hand to activate ability, like two specific cards not just from that clan and when you pull both you activate a great effect but when only one is drawn the card is left utterly "useless" js it's a guess lol not a great one but take it for what it's worth. feel free to expand on the idea
Tiwi`s Ability might be "Support Damage +1 "
a 3* common card with 7/3 stats and Ambre (might be there...I`m sure :weird
His/her bonus right now is unknown...what would the bonus be...???
Two clans have already a "Power +2" (Bangers and Ulu Watu)
"Stop Ability/Bonus" both bonus have already a two clans (GHEIST, Roots, Piranas, Nightmare)
"Damage +2" too (Fang Pi Clang and La Junta)
"Attack +8" (Junkz, Sentinels)
it could be boooring if the new clan has this bonus ↑↑↑
and it could be also boooooooring if it has the bonus of this clans ↓↓↓
All Stars, Berzerk, Freaks, Jungo, Montana, Pussycats, Rescue, Sakrohm, Skeelz, Uppers and lastly Vortex
