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
(2025-11-17) If a creature has +1/+1 counters and -1/-1 counters on it, state-based actions remove the same number of each so that it has only one kind of those counters on it
If the top card of your library is a creature, planeswalker, land, enchantment, or artifact card, it's also on the battlefield
With this many cards, most games will not even see half of the planar deck, which makes them less repetitive since there are always more lands to explore
From there, buff them with various artifacts and spells and create a cascading effect to take down that 40-person raid boss (or your friends).
