Give a new keyword "Sequence" to summarize the "second order" theme

The Second Order theme is exciting, but I noticed that it may be summarized by a keyword to simplify the card description. This would be crucial if we want more "second order" cards with more complicated effect in the future. Essentially, I suggest that we can define a keyword "sequence" to replace the clause "if this is the second order you give this turn", so the card description for "Wave After Wave" may be "Deal 2 damage to all enemy units. Sequence: Deal 4 damage instead.". By this way we can save a substantial amount of space for more description.

Well we can well change another word if there's any legal issue. In terms of mechanism, every CCG game shares some similar ones, like guard/taunt. There's no legal issue on that one
