Practice the Pix first, Q second weave: E a minion, ally, or enemy to move Pix, step off the wave so passive bolts are not blocked, then fire Q from the new line; that is a real Lulu lane skill, not just generic poke
In skirmishes, default to enemy-side W on the champion crossing the line first—the assassin, diver, or engager who decides the next two seconds—then use ally W only after that threat is already handled
Lulu’s bad games become winnable when you pick one enchantable teammate, stand just behind the body the enemy wants, and keep turning the same engage fake; recent data supports that she gets much more room to do this as games go longer
Ult the body the enemy is actually committing through, not automatically your ADC. If their whole plan is to dive your marksman, R the marksman early enough that the knock-up interrupts the contact and buys more autos. If your fed bruiser is the one forcing the fight and the enemy has to answer him first, ulting that bruiser can be stronger because it turns his entry into a wall they cannot cross cleanly. The bad Lulu ult is the late rescue after the burst already landed. The good one changes the collision itself, so the enemy loses access, spacing, or timing the moment they go in.
Pix fires magical bolts of energy whenever the champion he's following attacks another enemy unit. These bolts are homing, but can be intercepted by other units.
Pix and Lulu each fire a bolt of magical energy that damages and heavily slows all enemies it hits.
If cast on an ally, grants them Attack Speed and Move Speed for a short time. If cast on an enemy, turns them into an adorable critter that can't attack or cast spells.
If cast on an ally, commands Pix to jump to an ally and shield them. He then follows them and aids their attacks. If cast on an enemy, commands Pix to jump to an enemy and damage them. He then follows them and grants you vision of that enemy.
Lulu enlarges an ally, knocking nearby enemies into the air and granting the ally a large amount of bonus health. For the next few seconds, that ally gains an aura that slows nearby enemies.
