There are problems here.
1: Deja vus aren't really helpful at all in mono time.
2: sundials, as with deja vus, are not really helpful.
3: pharaoh, even with the shard, is not really helpful. More expensive then a dragon, and requires the shard to make any real use of the scarabs. Whom, by the way, would take 3 of to match the damage out put of one dragon on top of the 5 more quanta.
4: Much less of a problem, but could probably be replaced, the hourglass.
