Justification / Modifications:
One level of Shell Surf for escaping.
One level of Take Cover to avoid Stuns/Nukes.
Max Song of the Sea first since it is much easier to hit than Shell Surf and 3 Seconds silence is incredibly good and much better than the 40 extra damage from Shell Surf.

Starting Items:
Monkey Courier or Wards of Sight, Runes of the Blight, Health Potion, 3x Minor Totem, Mana Potion

Core:
Bottle >> Marchers >> Power Supply >> 1-2 Fortified Bracers >> Post Haste OR Plated Greaves

Bubbles is a ganker and thus profits a lot from Bottle and Power Supply. Basic Marchers are enough for the start.
Get 1-2 bracers to help him over his squishy-ness.
Post Haste are the best boots on him to be able to TP around the map and help pushing/defending. If you can't afford them get Plated Greaves.
Also dont forget to keep buying wards.

After Core:
Get those 4 items in any order. Start with the ones you need most. Frostfield Plate: If you need more initiation and if their team mainly consists of physical damage dealers.
Kuldra's Sheepstick: If they heavily rely on one hero to carry them.
Portal Key: Allows you to reliably escape after using Take cover.
Bloodstone: If none of the other options are a priority.

30-Seconds-Guide:
- In the beginning you should usually not put Take Cover on autocast and use it manually to dodge spells. Later you can put it on autocast. Unless you have very high APM to actually use it effectively.
- Shellsurf, Teleport -> Song of the Sea -> Kelp Field is a very strong gank combo starting in midgame.
- If you have a Portal Key you can use Take cover to let the 3 second cooldown on PK wear off and then blink away safely.
- Try to initiate next to the caster heroes to silence them asap.
- Bubbles is very flexible and fits most lineups and thus is most of the time a solid pick.

Counters:
- An early Mystic Vestments should help against the harassment.
- Bubbles has very low hp and can relatively easy be focused down.
- Bubbles is a ganking hero, so wards do a good job at seeing him coming and thus preventing you from getting ganked.
- Shell Surf can be dodged if you see it coming.
- Spread out in Team Fights so he can't hit all of you with his AoE Silence (500 AoE @ level 4)
- Vindicator's aura will make bubble's life hell. Not allowing him to TP to his shell and not allowing him to chain his spells.
