By the end of turn 6, Chapel had a deck of Chapel and 3 Silvers. By comparison, Remake had a deck of 3 Copper, 3 Estates, but 2 Silvers and a Gold. So, Remake has better buying power at the moment
No, it doesn't. The Chapel deck has an average draw value (ADV) of 6; the Remake deck has an ADV of 5. Next turn, Chapel deck has an ADV of 9 (it obviously buys a Gold). The Remake deck has an ADV of 5.9 if it buys a gold, 7 if it converts two Estates to Silvers, 6.7 if Remake hits C/E.
Also, perfect shuffle luck gets either deck 6 on T4. Chapel deck at T6 should be Chapel-GGSC with perfect luck (value 9 this turn, 11 next turn [trash C, buy G]); Remaking Coppers with perfect luck gets Remake-GGSCCCEEE (value 6.1 this turn, 7.5 next by Remaking Estates to Silvers).
Let's consider instead a Remake deck trashing Estates:
1/2: Silver/Remake
3: Rem-CEEE, trash EE, gain SS
4: SCCCC, buy G
5: Rem-SCCE, trash CE, gain S, buy S.
6: GSSCC, buy G or P.
Total deck after turn 6 is Rem-GSSSSSCCCCCC plus G or P. ADV: 7.3 on T5, 7.9 on T6 if a 2nd Gold is bought.
So, we have:
ADV on | Chapel Deck | Remake Estates | Remake Coppers |
T5 | 7 | 7.3 | 4.4 |
T6 | 9 | 7.9 | 6.1 |
T7 | 11 | 8.3 | 7.5 |
Two outstanding questions: (1) What if you buy a second Remake instead of the Gold on T4? Results won't really show until after T7. (2) Which strategy is more resilient to bad shuffle luck?
