Tips to maximize your impact

Land 4 autos before your Q
Land 4 autos before Snip Snip! (Q): each auto adds a snip, on top of the first and the last.
Hit with the center of your Q
Land the center of Snip Snip! (Q): in the center, part of the damage becomes true damage and each snip applies A Thousand Cuts (passive).
Mist against poke
Place Hallowed Mist (W) against poke and ranged CC: enemies outside the mist can't target you, except towers.
Use all three casts of your R
Cast all three Needlework (R) activations within 6 seconds: the first throws one needle, then three, then five, with growing damage.

How to counter and exploit weaknesses

Engage when his W ends
Engage when Bio-Arcane Barrage (W) ends: his attack range drops back to 500, and the spell has a 17-second cooldown.
Punish his lack of mobility
If you can engage, go for him: with no dash or leap, Kog'Maw can only back off on foot, and Void Ooze (E) is his only slow.
Leave his R range at low health
Below 40% health, get out of range of Living Artillery (R): each shot then deals its max damage to you, and it reaches very far.
Move away when he dies
When he dies, move away from him: Icathian Surprise (passive) makes him explode 4 seconds later, dealing true damage to nearby enemies.
