Other High-Power Creatures The first thing Id start looking for with a Ryu deck is high-power creatures that you want to attack with, and luckily, Boros has no shortage of goodies in that department
Leyline Prowler and Rattleclaw Mystic are nifty, but nothing will be better than a Birds of Paradise or Noble Hierarch for that early game goodness
You could replace this with one of the mana artifacts I mentioned earlier or like a Swords to Plowshares, Pongify, Rapid Hybridization, Path to Exile (I kind of think you need some more removal lol, but you could replace Verity Circle with whatever you wanted.) Remove Alive / Well
and shares similarities with most other summoning techniques
While a player wants to destroy/exile an opponent's Planeswalker and spends resources to do so and their opponent dedicates resources to protecting it, the roles are reversed with Battles, as its controller wants to dedicate resources with attack and damage their permanent, while the opponent must prevent its counters from being reduced to zero in order not to deal with a greater threat
