I'm also bullish, but I don't think we're going to see the same price increase simply because there are way more Chaos Legion cards released right now than there have ever been Untamed cards released and we're not even halfway there yet. So there will be less scarcity, so lower prices, although they will increase once Chaos Legion is sold out.
But if you wait long enough, buy the right cards and if only enough new players come into Splinterlands, anything is possible!
