Security Rhox lets your creatures attack into any board without fear of chump blocks — opponents can't assign blockers with power less than Security Rhox's own power. Six mana for a 4/5 with no evasion of its own is a steep ask, and that cost keeps it out of most competitive lists.

Security Rhox is a Commander card, full stop — the 100-card singleton format gives it room to find niche homes in go-wide or Voltron strategies that need to punch through stalled boards. In Modern, Pioneer, Legacy, and Vintage, six mana for a creature with no immediate impact and no protection gets you nowhere near a competitive gameplan. Even in Commander, Security Rhox competes against cheaper, broader answers to chump-block walls, so it earns a slot only when your deck specifically rewards forcing combat damage through.

Price Context
Current price
$0.04 bulk tier
At $0.04, Security Rhox is deep bulk — the kind of card you pull from a common box rather than buy. Price stability is irrelevant at this tier; it costs essentially nothing to try and nothing to cut.
