Talon vs Rammus

Apply three Blade's End (passive) stacks by hitting with your spells, then strike with an auto: the target starts bleeding and takes heavy damage over time.

Cast Noxian Diplomacy (Q) in melee range when you can: instead of the leap, it lands a critical strike. If it kills, it heals you and comes back faster.

During Shadow Assault (R), break invisibility with an auto or Noxian Diplomacy (Q): the blades then converge on your target instead of coming back to you.

Push your wave, then roam by vaulting walls with Assassin's Path (E): the spell comes back fast, but you can only cross the same wall again after a long delay.

Stay behind your minions: Powerball (Q) stops on the first enemy it collides with, minions included.

If you deal magic damage, lean on it in trades when Defensive Ball Curl (W) is on cooldown: without it, his resistances drop to those of an ordinary tank.

If you're ranged, don't let him reach melee range when Frenzying Taunt (E) is ready: its range is short, and it forces you to attack him.

Get out of the Soaring Slam (R) area fast: aftershocks repeat the slow there, and if cast during Powerball (Q), it adds a knock-up in the center.

Don't attack during Defensive Ball Curl (W): each auto returns magic damage to you, and he gains armor and magic resist.
