Malphite should focus on surviving early poke and avoid extended trades until armor and cooldowns provide safety against Teemo's ranged harassment.
Prioritize stable lane control to reach level 6 where (R) enables impactful engages and teamfight presence.
Trading pattern
Use measured (Q) poke to chip Teemo while relying on (E) to blunt his auto-attack damage during trades.
Avoid trading when your passive shield is down or (R) is unavailable, as your threat and durability are reduced.
Punish (Q) cooldown by stepping forward for short trades when blind is down, but do not overcommit before armor stacks.
Danger windows
Be cautious when (Q) blind is available, as it negates your auto-attack damage and trade effectiveness.
Avoid prolonged exposure to Teemo's trap zones, especially before you have sweepers or team support.
Recognize that before level 6, your engage threat is low, so avoid risky all-ins or extended trades that Teemo can punish.
Early game
Play cautiously in early levels to minimize damage from Teemo's ranged autos and (Q) blind, using (W) to boost armor and (E) to reduce his attack speed.
Avoid wasting mana on low-value (Q) poke; instead, farm safely and preserve resources for level 6 all-in potential.
Maintain vision and sweep for traps to reduce surprise damage and control from (R).
Power spikes
At level 6, use (R) to initiate fights or ganks with guaranteed knockup, forcing Teemo to respect your engage threat.
After completing your first armor item, take safer trades as Teemo's auto-attack damage is significantly reduced.
Respect Teemo's level 6 trap control with (R), and sweep or avoid trapped areas to prevent poke and zone control.
Win conditions
Survive the early lane poke by stacking armor and using (E) to reduce Teemo's attack speed, then leverage (R) at level 6 for decisive teamfight engages.
Deny Teemo the chance to control side-lane paths with traps by sweeping and maintaining lane pressure without overextending.
Focus on grouped fights where your (R) can initiate and your tankiness can absorb damage, leading your team to victory.
