Is this really necessary?

What about actions like:

• Sell a new installment DEC-B.
• Price cards like Zyriel more reasonably so that more people buy them, how about e.g. just 40,000 DEC instead of 40,000 DEC + 160 vouchers? Would certainly burn significantly more DEC.
• Demand entry fees for tournaments in DEC instead of SPS (prices still in SPS).
• Generate a new must-have promo card and sell it for DEC, e.g. a neutral Summoner with which you can really play all cards from all Splinters, e.g. for 10 mana
• Pay leaderboard price in SPS instead of DEC.
