Hey, everyone, I'm a really new Magic Player and I'm looking for some help on how to improve this deck that I built to play against a friend of mine. Any criticism will be welcomed.

My main goal in this deck was to use the the ability to gain life to boost Ajani's Pridemate and add tokens with Regal Bloodlord and then hopefull have Ajani's Welcome trigger with Regal Bloodlord and Leonin Warleader. I could definitely use some tips. I'm trying to avoid using cards that will rotate out of standard this year. I'm also a pretty new payer, so I don't have many cards, but I am open to getting whatever I need.
