The "Life Boost" deck lets you build your own army of Soldiers, with Angels to lead them. To win with this deck, play your small creatures as quickly as you can to deal some early damage. If your opponent manages to hold off your attackers, build a strong defense. Then you can start cautiously attacking again to get in those final points of damage.

Half your creatures cost only one or two mana to play, so you can get them on the table quickly. Attack with swarms of your small creatures if you can get some damage through, even if that means you lose a creature. If your casualties become too great, hold off until you have enough mana to play your bigger creatures, such as Angel of Mercy. You can also make all your little creatures bigger with the enchantment Glorious Anthem. Giving your entire army +1/+1 makes it a force to be reckoned with.

It's okay if you take some damage early on. The deck has many cards that raise your life total, including creatures that give you life when they come into play. But try not to use the Healing Salve just to gain life unless you're about to lose. You can put it to better use saving one of your creatures that would otherwise take lethal damage.

Gaining life is great, but don't let up on the attack. If you don't deal damage to your opponent, the highest life total in the world won't matter. Use your flying creatures to soar above your opponent's forces. Also, Seasoned Marshal is a great leader for your ground troops. When it attacks, you can tap your opponent's biggest defender to help your army punch through.

What else can you do about your opponent's creatures? Crossbow Infantry can take care of the smaller ones. Keep one Crossbow Infantry untapped and your opponent won't want to attack or block with small creatures. You can use Chastise, Pacifism, or Spirit Link to protect yourself from huge creatures. Remember that if you play Spirit Link on an opponent's creature, you gain life every time it deals damage!
