Some Purple (tactics-type) cards can do direct damage to enemies in a lane, with the exception of armored units. Only use them when you are sure you can get a kill. This will prevent your opponent from building up their forces and gives will you more control over a lane without risking troops.

Some tactics cards can boost your troops' damage output. Use them on Push-type cards or on any of your cards when you have units next to your enemy's headquarters.

Bikers and other units have double movement speed. If your enemy is restricted to a single lane, drop Bikers into open trenches to reach their headquarters quickly.

Some cards create multiple copies of a unit. However, they usually have low starting health and must be protected behind an established powerful lane.

Reduce the excess numbers to one then multiply it by a number you can use to summon. Although you will lose extra summoning resources, you will get them back.

Green (push-type) cards have high health, low attack, armor to reduce damage, and will push back offensive units. Place them in front of an attack to protect your gunners. After awhile, place them in the rear of your lane to prepare another offensive wave.

Use push-type cards to defend low-priority lanes. Using a single high health push-type card in non-essential lanes can slow your enemy's progress long enough to allow your main lane to win.
