Let’s look at some life gain synergies you can use in this deck. The most popular one is Ajani’s Pridemate. Gideon’s Company is a more expensive version of the Pridemate but it gets two +1/+1 counters and you can pay 4 mana to put a loyalty counter on a Gideon planeswalker if you have one. You don’t have to run these two, but if you are on a budget, go ahead. At the very least they can help draw fire (single target removal spells) away from Darien, King of Kjeldor. Archangel of Thune puts a +1/+1 counter on all of your creatures whenever you gain life, buffing your entire board. You can also use the infinite combo of Walking Ballista and Heliod, Sun-Crowned. Not to mention you can sacrifice a ton of tokens to Ashnod’s Altar giving you two mana each for the Ballista. Also, if you opponents realize that attacking you just helps your game plan and stop attacking, you can start pinging yourself with the Ballista if you need more tokens. Combined with Heliod, you give the Ballista lifelink and start removing +1/+1 counters to ping yourself, dealing 1 damage to you, but since the Ballista has lifelink you heal for that 1 damage which triggers Heliod allowing you to replace that +1/+1 counter and get a token while Darien, King of Kjeldor is in play, and you can start the cycle all over again gaining an infinite number of Soldier tokens. Of course you can also just use it to ping an opponent to death too, but where’s the fun in that? This combo can also be pulled off at instant speed so you can create a ton of blockers if your opponent happens to have like a 60/60 or something ridiculously huge that wipes you out in one hit. There are so many options with this combo, some of them game ending.
