Warrior's Resolve

Training is a keyword built for aggressive boards, and this enchantment turns it into a repeatable draw engine by grafting a card-advantage clause onto the mechanic itself. Handing every creature you control training means your attacks compound: the smaller attacker collects a counter each time it swings alongside something bigger, so a wide board grows itself without spending cards to do it. The second ability is what elevates the design past a simple pump effect. Once any of your creatures carries a +1/+1 counter and has attacked, the end step hands you a card, converting the incidental counters training produces into a resource stream. The two halves lock together cleanly: training generates the counters, the end-step check cashes them in, and the whole thing runs off combat you were going to make anyway. What stops it from becoming free card advantage every turn is the sequencing: the counter has to already exist and the creature has to have attacked, so a stalled board or a turn spent holding back gives you nothing. It rewards the specific texture of a go-wide white deck with a power curve among its attackers, where the size disparity that makes training awkward on a single creature becomes an asset spread across a team. As a support piece rather than a bomb, it fills the role white has always wanted from its token and aggro shells: turning a committed attack into gas instead of an empty hand.
