Do you like doing stupid long chains of effects requiring perfect timing for minimal reward pay off? Then you will love this grandracmon deck.
Everything works like the basic gran drac deck but a particularly intresting combo you can put using skullbaluchimon in combination with the dracmon inheritable means you can basically use skullbaluchi to rush into any mega for a high cost of memory.
Digivolve up to grandrac. Play out a dracmon. Ignore the search and end of attack digivolve into rush Blackgato. Swing and tap sora&mimi to trash skull baluchi, activate skullbaluchi effect to immediately digivolve into skullbaluchi on Blackgato. This digimon gains on deletion delete one of you opponents digimon. Then activate the inheritable of dracmon to digivolve again into Venommyotismon to gain an additional sec+1 on a hail mary swing. At the low cost of 7 memory you managed to do 2 checks with 12k and retain the on deletion effect to delete an opponents digimon. Venommyotis will also gain retaliation to gain more deletion protection. This means you will most likely keep the annoying effect of gaining 1 memory every time your opponent suspends a digimon. Your opponent now has a surplus of 7 memory to swing around your digimon.
Blocker retal with dexdoru combined with skullbaluchi is the winning combo for the deck. Any time you digivolve to dexdoru from trash if you have skullbaluchi in hand its best to immediately gain the 1 memory and go to skullbaluchi to get a blocker with retal and on deletion delete a digimon. This is the primary form of survival in this deck as it will take a long time to pull of the major combos of the deck.
Everything costs lots of memory and there is very little memory gain. Expect to pass your opponent with a lot of memory unless you have a good tamer setup.
When the deck is going its going but getting it right is extremely difficult and the massive amount of memory it takes to make every play happen usually leaves you with 1 big digimon stack just sitting around to be deleted.
