With Against the Shadow, both heroes and minions get small faction-boosting cards that can add some crucial marshalling points in small bits rather than big chunks. The hero card, No Strangers at This Time (reviewed earlier), is technically played on the site, although it requires a faction in order to exist. Tribute Garnered is the minion version, more limited in some ways and yet far more flexible in others.
The nicest thing about this card is that it is a free MP, always playable - unless you don't have a faction in play, of course, in which case you had better get cracking. As a resource, it can be played at ANY time during your turn. You can toss it down on a faction immediately after recruiting it, but you can also play it on a faction that was played several turns ago. You can play it during the movement/hazard phase instead of having to discard a card. If you discard & draw it during your end-of-turn phase, you can quick play it then just before your opponent's turn. There are NO limitationson when you can play it, no tapping, nothing, and it's worth an MP - who could ask for more?
And so, appropriately enough, its limitation is devastating - it's discarded when any play deck is exhausted. That limitation is normal for a number of hazard permanent-events, but for a MP card, the implications are far more serious. Especially now that 2-deck games are the norm, it's pointless to put this card in your deck and play it on a faction in, say, the third turn, because before the game is over, SOMEONE will have to cycle their deck, and you'll lose the card. There is no point whatsoever in playing this card until both you and your opponent have cycled through your decks. Otherwise, for all the ease in playing it, it's going to go away just as easily.
All of this makes Tribute Garnered ideal for endgame. It begs, nay, DEMANDS to be put in the sideboard. When you cycle your deck, you can move up to three of them into your play deck, and for those last turns of the game when you and your opponent are on the second swing around, you can draw and play it easily and without much fear. You should certainly have a faction in play by that point - if you don't, your troubles are just beginning. So what Tribute Garnered amounts to is a trickle of free points at game's end - I'll take that any day.
I can think of precious few reasons not to include 3 Tribute Garnereds in each and every minion sideboard. There are ways that the second-deck free points could be thwarted, of course - in a very close 2-deck game, things might not end until someone cycles their deck TWICE, in which case all those points are lost. Once you have a TG or two in play, your opponent knows that keeping the game going until a second cycle will mean snatching a couple points away from you, and can use that to their advantage. And, if for some reason your game never makes it to the FIRST cycling of decks (for example, in a timed tournament setting against a slow opponent), there not much point in having TG at all. But that's all the more reason to play briskly and cycle your deck as quickly as possible - with Tribute Garnered, you're guaranteed candy on the other side.
