This really depends on how repeatable you want it to be, but Isochron Scepter, Eternal Witness work with any enchantment removal. Similarly Evolutionary Leap can repeatably tutor up creatures that potentially serve as enchantment/artifact removal (it's no Birthing Pod though). In the same vein, Snapcaster Mage make some spells repeatable.
I think a better question is why do you need repeatable artifact & enchantment removal. What is actually giving you trouble here? Most of the multiple use stuff is either over costed or so narrow in application it isn't good enough for modern.
Unfortunately every try hard from Sacramento to Shanghai preaches from the top of their 27 lands + Mana Reflection that Tooth and Nail and Time Stretch are fine to play in the same turn but Armageddon is unfair.
