Crested Dragon
AUTO [Rearguard Circle]: When it attacks a vanguard, if the number of your opponent's rearguards is 3 or less, this unit gets Power +5000 until end of battle.
Stardrive DragonAppropriately for Royal Paladin and Kagerо̄, the new Stardrive and Crested Dragons are essentially inversions of each another's conditions, with Stardrive gaining power based on increasing your own rearguards and Crested gaining it based on reducing the opponent's. Their SD incarnations instead gained just 3k power, but those versions were active in both vanguard and rearguard circles, and both required their fighter to have three or more rearguards in play.

The 5k power bonus means that the new cards can swing for 18 alone, which meets the base requirement to force the opponent to guard with 10k shield. (13 being the normal base power for a grade 3 vanguard in Standard.) With as low as a 5k boost these cards can go for 23k and force a guard with a Critical Trigger or better, but the problem is reaching the stage after 23. 28k is the threshold at which rearguard columns become truly threatening in the Standard format, and the only way for these cards to reach that threshold is with Allen, Marron, Gojo, or Auspice Falcon. These cards each have skills capable of powering up either themselves or these attackers, bringing them in the range of 28~29k. Without these specific units, there isn't a tangible difference between the SD and TD versions of these cards, as virtually any booster will make a 23 column with the Start Deck versions.
No matter which version is your preference, they each have the Force icon, granting you another instance of a continuous +10k during your turn to a circle of your choice--for the rest of the game. That brings us to an important issue with these cards; they contradict the goals of your deck.
In the new format, the ideal play strategy is to continuously ride another grade 3 every turn from the first moment possible, gaining another instance of your clan's Imaginary Gift to further strengthen your board and force additional guard from the opponent. (Or in the case of Protect, progressing another step on the long road towards an unbreakable defense.) Playing grade 3s with a Gift to the rearguard directly contradicts the ideal flow of Standard decks. Vortex Dragon and Gigantech Charger can get away with it because these cards don't have Force, and as a trade-off are capable of a much higher maximum threshold of power than Crested or Star Drive, with Vortex getting 5k every time you use Bahr, Burj, Berserk Dragon, or Spillover, and Gigantech getting 10k on-place or when you ride.
What this means in the long run is that the Start Deck versions are preferable because these at least can make a power difference on the vanguard circle with base 7k grade 1s or with vanguard-specific boosters like Miru Biru. The Trial Deck equivalents are vanilla 13ks on vanguard, and if you were going to run them for their rearguard boost then you would find better versions of that strategy waiting in BT01. (For $0.50 and $0.25 per card, at that!)
At the end of the day, the Start Deck vs Trial Deck version debate won't have long to live. The Trial Decks hit June 8th for the English format, and we move on to BT01 format just 22 days later. By then multiple new grade 3s will have likely swept all this under the rug. But for those 22 days, it's probably best to switch these units out for their Start Deck prints.
With these two cards out of the way, we have one final set of uncertainties regarding the Trial Decks; whether or not the grade 1 perfect guards will differ from their Start Deck counterparts, and if any of the triggers will be effect triggers.
