Tips to maximize your impact

Aim for isolated champions
Aim Lay Waste (Q) at a champion away from their minions: if the blast hits only one enemy, it deals much more damage.
Wall before your combo
Place Wall of Pain (W) in their path before your combo: anyone who crosses it is slowed and loses magic resist.
Keep playing after you die
After you die, keep casting your spells: Death Defied (passive) keeps you in spirit form for a while, and you can still cast Lay Waste (Q) and Requiem (R).
Requiem for the finish
Save Requiem (R) to finish off wounded enemies, often right after a teamfight: it hits every enemy champion wherever they are, after a 3-second channel.

How to counter and exploit weaknesses

Walk around his mines
Walk around Hexplosive Minefield (E): each mine explodes on contact and slows you, which helps him land his other spells.
Engage after his Satchel Charge
If you can engage, go in right after Satchel Charge (W): it's his only way to get away, on a 20 to 12 second cooldown.
Get out of the center of his bomb
If Mega Inferno Bomb (R) lands on you, at least get out of the center: the center of the blast deals more damage than the edge.
