How To:
press R at spawn so u got the active. start at red or invade their blue. after u hit red buff activate R again so u get the active again. after u got red u do wraith -> wolves -> blue buff > big wraith. now do wolves again or gank mid/top. be sure u got enough gold for madreds when u go back to spawn the first time. now gank and farm until u can buy wriggles lantern. if u got wriggles go and stack it up to feral flare but dont forget to gank lanes if somebody needs your help (thats my way, some people will probably tell u to ignore lanes and stack feral up but i dont like this ^^). when u reached zephyr u are able to backdoor (xpeke), just tell your team they should push top or bot and u do the tower on the other side while the enemys deffending against your team (this needs a bit of practice).

Fight: Beginn with Q -> after hit switch to R -> after hit E -> after hit back to Q and now once again to R than E and so on. activate W also if u receive damage.

U can also play Udyr top like this and buy randuins instead of wriggles but trinity and zephyr first then.
Ablity stacks (tiger stance udyr): Q,E,W,Q,Q,Q,W,Q,W,W,W,E,E,E,E,R,R,R

Now have fun and do pentas ;)
