Zodiac deck best Voucher Farm?

So as of today, I only have to find the Hand Size voucher 2nd tier and the Diamond specific Joker.

As such I've been mainlining the Zodiac deck to lower the pool of available vouchers and am constantly rerolling for new Jokers (no luck yet)

Is this the optimal path or is there another strategy for hounding down these last 2 missing spaces in my collection?
