Tahm jungle

so, i've been playing Tom (tahm) in all positions save adc and mid sense he was released with fairly good successes. and have been wining just bearly more jungle games with him than i feel i should be. just a bit more than high 50%.

my normal build path is(seriously) sated devourer, swifty boots, phozen mallet, spirit visage, sunfire, warmogs.

i tend to do enough damage to 1V1 most anyone who trys to fight me once i get mallet and before then i gank decently even thought i pretty much only have the Q to slow them and maaaaybe a W to pull them back on a good gank.

my biggest question is if this supposed to really work? does anyone else use this to good effect. am i a weirdo? is my luck running out?!.
