Tapping an Equipment this way wont affect its abilities or the equipped creature
Its worth noting that Sorin requires some sacrifices, so that pulls us in a direction further away from the current white aggro decks
For example, if you gained 3 or more life during your upkeep and you cast Sorin of House Markov during your first main phase, its last ability will trigger at the beginning of your postcombat main phase
Finally, each of those cards are converted into a fully specified JSON object using the processes I described above, and the Magic Set Editor is used to turn them into full cards With all these steps together, the program is able to create a pretty coherent set
Im not sure the juice is worth the squeeze yet
The flashback mode is comically expensive though, so I wouldnt count on it much
