The original guide, Anokuu's Guide to Master the Master, was originally posted by /u/Anokuu on /r/Diepio.
The Shooting Star technique can be used by making all your Factory drones follow your mouse, and keep it in front of you to avoid bullets. This is done to protect yourself from bullets, since the minions can instantly respawn in front of you and can take multiple bullet hits.
In order to trigger the Shooting Star, one must hold shift or right-click continuously and hold their mouse in front of their tank. You must also disable Auto Spin using C, but having Auto Fire (toggled by E) is optional.

If the minions are close enough and within the 'Leash Zone', they will form a Shooting Star.

With this protection, you can now ram someone, or start using your minions normally. The option that is most effective would depend on your build and your opinion. If you have a build with higher movement speed and body damage, ramming would most likely be more effective.
/u/Anokuu describes it this way:
Use the spinning attract to attract all 6 minions (become a star shape), then charge towards the opponent with the minions as shield in front of the Master. When moving toward a direct along with minions leashed, if you have the same movement speed as bullet speed (For example, 7 bullet speed and 7 movement speed), you don't need to move the mouse because they have the same movement speed as you do.
You can watch a fight against two experienced players, with the first using the Shooting Star tactic and the second using Penta Shot, on YouTube.
Are you level 30 yet? Apparently you need to be.
From the Wiki:
The Smasher is one of the five basic upgrade choices from the Tank. Unlike other Tank Upgrades, it becomes selectable at Level 30. It may further upgrade into the Landmine, the Auto Smasher or the Spike.
It's considered one of the basic upgrades because it would be the first upgrade you make if you chose to wait until level 30. I'm assuming that the diagram above is tiered out to the corresponding levels you need to be to upgrade to that tank (meaning the Smasher tank is in the level 30 tier), but having never played the game, I can't say for sure.

In the top-left corner, you can select which tank you can upgrade to. As a Basic Tank, you'll most likely see this:
If you reach level 30 as a Twin, you would see a different list of upgrades.
If you press the gray Ignore button below the upgrades, the Upgrades menu will slide out. It will return again if you hover your mouse near the top-left corner. It will also automatically reappear if you reach levels 30 or 45. If it will not appear even when hovering your mouse near the corner, it is probably because you don't have any available upgrades.
