For this guide to work to its fullest you may want a good friend to play with you as ad thresh or ad blitscrank in the bottom lane.(believe me it dominates)

This is a great build for your Senpai Blitzy

step 1:Farm till ult level.
Step 2:If blitz/thresh pulls someone fight them so you may level up to shrooms level faster.
Step 3:Once you hit shrooms level play shrooms strategically so that you opponents will walk into them then go invis on top of them(if you are not playing with blitz/thresh or just by yourself this step may require some baits) Then let your partner pull and raep them.
Step 4:get fed rinse and repeat

aka once you hit 6 to get shrooms just stand still on top of shrooms q and attack with your e.

This Guide is made just to empower your shrooms, and to bring them to their best potential

This build works for top mid and bottom lane.

I recommend bot lane so that you can have a friend to pull someone.(Its a lot of fun)

This build works very well, and no is not supposed to be a troll build. my first game with this build I went 10/3/10 with a surrender at 20
