Repeatable rewards for Training Grounds

knifelheim

I would really like to see Training Grounds (or some other, similar event) have repeatable rewards. It's really stupid that there are times where there is simply nothing else to do in MtG:PQ. I will log in, check the events, and see that there's nothing available except training grounds, which I've already completed the rewards for (and then some) and then just log back out. There needs to always be something to do. Would it be that crazy to make the rewards cycle so that once you've reached your 4th win in Training Grounds, you start over at reward 1? you can slowly grind up mana runes and crystals and have something to work for.
