"If the Eucharist were just ordinary bread and wine with no miraculous element to it, then the new manna would be inferior to the old. But that’s a no-go when it comes to Biblical typology. The New Testament fulfillment must always be greater than the Old Testament type."
Jesus Christ, the new manna, is superior to the manna given in the desert because the nourishment that He provides is life everlasting. The manna given to the Israelites was designated to satisfy physical hunger and was thus temporal. Christ is to be spiritually consumed by faith and not by literally eating His flesh and drinking His blood.
"...If real blood was used for the ratifying ceremony of the Old Covenant, then how much more need there be real blood for the ratifying ceremony of the New Covenant, which is the Last Supper?"
The "real" and "substantial" blood of the New Covenant was shed on the cross. The wine at the Last Supper simply pointed to that reality.
