The effects on these cards are extremely powerful, and can easily turn the game in your favor for no real in game loss
Srams ability draws a card when you cast an aura, equipment, or vehicle, so the majority of cards in your deck are functionally cantrips

Standard only uses two different strong dual land cycles per year, and some more budget options like Gates and gain lands, but with only two years' worth of cards, there just aren't many options
However the Minion Reflector trigger still goes on the stack, and so copies the Last Known Information about the creature, and so it copies all 'copiable values'--specifically 'Other effects (including type-changing and text-changing effects), status, and counters are not copied.'

Its second ability is also very titan-cycle-esque, stating that whenever Blight Titan enters the battlefield or attacks, mill two cards, then incubate X, where X is the number of creature cards in your graveyard
