Though not always the case, creatures with defender often have low to no power and high toughness
I dont think mono-red players are starting this card in their initial 60, but its awesome in your sideboard as a way to fight midrange and control builds
The problem is that the solution was shortsighted (understandably, as not many people in the mid 1990sincluding Wizards would have predicted that Magic would grow into what it is today) and everlasting
Cards like Rampant Growth, Migration Path, and mana-fixing artifacts such as Chromatic Lantern and Arcane Signet make sure you have the resources to summon your dragons ahead of schedule
The fewer cheap artifacts you play, the less powerful Urza becomes, and I like that its activated ability suggests playing more proactive spells or permanents, rather than the control role that many mono-blue decks tend to lean into
